How to Hang a Baby Mobile: Complete Guide
Hang your baby mobile using a crib-mounted hanger arm (easiest), ceiling hook (cleanest look) or freestanding floor hanger (most flexible, no drilling). Position the mobile at least 40 cm above the mattress, slightly toward the foot of the cot, and always ensure it is completely out of your baby’s reach.

Choosing Your Hanging Method
After two decades of helping Australian families install baby mobiles, I can tell you that the hanging method matters just as much as the mobile itself. A beautifully handcrafted mobile hung incorrectly loses its visual impact, fails to rotate properly and — most importantly — may pose a safety risk.
There are four main ways to hang a baby mobile in an Australian nursery, and the right choice depends on your cot style, ceiling type, tenancy situation and personal preference. Let me walk you through each one so you can make a confident decision.
Before we dive in, it is worth noting that whichever method you choose, the fundamentals remain the same: the mobile must be secure, out of baby’s reach and positioned for optimal visual engagement. Our correct placement guide covers the positioning principles in detail, while our hanger selection guide helps you match the right hardware to your nursery.
Quick Overview of Options
- Crib-mounted hanger arm — Clamps to the cot rail. No drilling required. Most popular choice.
- Ceiling hook — Screws into a ceiling joist. Gives a floating, minimalist look.
- Wall bracket — Fixed to the wall beside the cot. Good for cots positioned against a wall.
- Freestanding floor hanger — Sits on the floor beside the cot. Zero installation, maximum flexibility.

Step-by-Step: Crib Arm Installation
The Mumbi Hanger Arm ($79.99) is the most popular hanging method among our customers, and for good reason. It requires no tools, no drilling and installs in under two minutes.
What You Need
- Hanger arm with clamp mechanism
- Your baby mobile
- Measuring tape
Installation Steps
- Choose the position. The ideal spot is at the foot-end of the cot, slightly off-centre. This places the mobile within your baby’s natural line of sight without requiring them to crane their neck. See our placement guide for detailed positioning advice.
- Open the clamp. Loosen the clamp mechanism and place it over the top rail of the cot. Ensure the padding sits flush against both sides of the rail.
- Tighten securely. Hand-tighten the clamp until it grips firmly. Give the arm a gentle tug to test stability. It should not move or wobble.
- Hang the mobile. Attach your mobile to the hook or loop at the end of the arm. The Mumbi Felt Baby Mobile ($59.99) hooks on instantly.
- Measure the height. Use a measuring tape to confirm at least 40 cm clearance between the mattress surface and the lowest element of the mobile.
- Test rotation. Give the mobile a gentle push. It should rotate slowly and freely without touching the arm or cot sides.
Step-by-Step: Ceiling Hook Installation
Ceiling mounting gives the most dramatic visual effect — the mobile appears to float above the cot with no visible hardware. It does require more effort, but the result is stunning.
What You Need
- Ceiling hook rated for at least 5 kg
- Stud finder (for locating ceiling joists)
- Drill with appropriate bit
- Fishing line or clear nylon cord
- Measuring tape
Installation Steps
- Locate a ceiling joist. Use a stud finder to locate the nearest joist above the cot. Never screw into plasterboard alone — it will not hold the weight reliably.
- Mark and drill. Mark the hook position directly above the foot-third of the cot. Drill a pilot hole into the joist.
- Screw in the hook. Thread the ceiling hook into the pilot hole until it is flush and firm. Test by pulling firmly with your hand.
- Attach the cord. Tie clear nylon cord to the hook. Measure the length needed to position the mobile 40+ cm above the mattress.
- Hang and level. Attach the mobile and adjust the cord until the mobile hangs level and at the correct height.
If you are renting and cannot drill into the ceiling, consider the Mumbi Wooden Hanger ($69.99) or Floor Hanger ($129.99) as drill-free alternatives.

Using a Floor Hanger
The Mumbi Floor Hanger ($129.99) is the most versatile option. It requires zero installation, can be moved anywhere in the nursery and doubles as a tummy-time mobile stand.
When a Floor Hanger Is the Best Choice
- Renters who cannot drill into ceilings or walls
- Parents with multiple rooms who want to move the mobile between bedroom and living area
- Tummy time — position the mobile at floor level for supervised play
- Older babies (6+ months) who have outgrown cot-mounted mobiles but still enjoy watching them
Setup Tips
Place the floor hanger on a flat, stable surface beside the cot. Ensure the base is positioned where it will not be kicked or tripped over during nighttime feeds. Adjust the arm height so the mobile hangs at the correct viewing angle for your baby. The weighted base keeps everything stable even on carpet or uneven flooring. For more detail on how this fits into your nursery layout, see our deciding where to put your mobile guide.
Height and Positioning Guide
Height is the single most important factor after choosing your hanging method. Get it wrong and the mobile is either invisible to your baby or dangerously within reach.
Height Guidelines by Age
- 0–6 weeks: 25–35 cm above mattress. Newborns have a very limited focal range and need the mobile close to engage with it.
- 6 weeks – 3 months: 35–45 cm above mattress. As focal range expands, raise the mobile slightly.
- 3–6 months: 40–50 cm minimum. Your baby can now reach, so maintaining height clearance is critical for safety.
Horizontal Positioning
Position the mobile slightly toward the foot of the cot — not directly above your baby’s face. This encourages natural eye tracking and reduces neck strain. The mobile should be visible when your baby is lying on their back looking slightly downward. Our correct placement guide has diagrams showing the ideal zone.
Rotation Space
Ensure the mobile has at least 15 cm of clearance on all sides to rotate freely. If the mobile brushes against the wall, cot side or hanger arm, it will not move naturally and will lose its calming effect. This is particularly important with the Animal Baby Mobile ($69.99) and Space Baby Mobile ($69.99), which have slightly wider profiles.
Safety Checks After Hanging
Once your mobile is in place, run through this safety checklist. Australian standards (AS/NZS 8124) require that nursery products meet strict safety criteria, and proper installation is your responsibility as a parent.
Essential Safety Checklist
- Tug test: Pull the mobile firmly in every direction. It must not come loose or shift position.
- Reach test: Place your baby in the cot and observe. Can they touch any part of the mobile? If so, raise it immediately.
- String check: Ensure no strings, cords or ribbons dangle within reach. All cords should be shorter than 20 cm and firmly attached.
- Weight check: Confirm your hanging hardware is rated for the weight of the mobile plus a safety margin. A typical felt mobile weighs 200–400 grams.
- Part integrity: Check that all mobile elements are securely attached. No small parts should be removable by pulling or twisting.
Ongoing Maintenance
Inspect the mobile and its mounting hardware weekly. Check for loosened clamps, fraying cords or worn attachment points. Tighten or replace anything that shows wear. As your baby grows and becomes more active, increase your inspection frequency. For additional safety considerations, see our crib attachment guide and our troubleshooting guide.

When to Rehang or Reposition
Your mobile setup is not a set-and-forget arrangement. As your baby grows, you will need to adjust the height \u2014 typically every four to six weeks during the first few months. When your baby begins rolling consistently or pushing up on hands and knees (usually around 4\u20136 months), it is time to either raise the mobile significantly or transition to a floor hanger positioned beside the cot rather than above it. If you are also considering how mobiles support your baby\u2019s sleep, our role of baby mobiles in sleep guide explains how the hanging position affects bedtime routines. For parents exploring different mobile themes \u2014 from Moon ($59.99) and Cloud ($59.99) to Dinosaur ($59.99) \u2014 the hanging method remains the same across all Mumbi mobiles. Our when to start using a baby mobile guide covers the developmental timeline that determines when adjustments are needed.
