Crib transition: when and how to move from bassinet to crib

The move from bassinet to crib is needed when the bassinet becomes too small, your baby moves more or the manufacturer gives a weight or developmental limit. It should not be rushed; it should be safe.

This guide connects with safe baby sleep, room sharing and the night routine checklist.

When to consider it

Consider the move if:

• your baby often touches the sides;
• they try to roll or push up;
• the bassinet is past the manufacturer's limits;
• a more stable space is needed;
• the mattress no longer stays perfectly flat.

Always check the product's real instructions and limits.

The crib stays empty

A crib needs a firm mattress, fitted sheet and nothing else. Avoid pillows, bumpers, toys, heavy blankets, soft inserts and positioners.

How to do it gradually

You can start with:

• one nap in the crib;
• the same evening routine;
• the same sleep sack if already used safely;
• washed familiar sheets;
• familiar room and lighting;
• a few adjustment evenings without changing everything else.

If your baby protests, return to a calm sequence. You do not need to change feeds, timing and place on the same day.

Parents' room

In the early months, safe sleep recommendations favor keeping your baby in the parents' room, on a separate surface. If the crib fits in your room, it can be a good transition option.

Key takeaway

The bassinet-to-crib transition does not need to improve sleep at all costs; it needs to maintain safety and predictability. To monitor the effect on nights, use the sleep diary tool.
