When to Move from the Bassinet to the Crib (and How to Make It Smooth)

“How do I know when my baby is ready to move from the bassinet to the crib?”The bassinet-to-crib transition can feel emotional, confusing, and even a little scary—especially if your baby has been sleeping well!

The good news? This transition doesn’t have to disrupt sleep when it’s done at the right time and in the right way.

Let’s walk through when to make the move and how to do it successfully.

When Should You Move from the Bassinet to the Crib?

Most babies transition to the crib somewhere between 3–6 months, but readiness matters more than age. Here are the most common signs it’s time:

1. Your baby has outgrown the bassinet:

If your baby looks cramped, is bumping the sides, or is close to the weight or height limit, it’s time. Safety always comes first.

2. Your baby is rolling or trying to roll

Once rolling begins (or is close), many bassinets are no longer safe.

3. Sleep is becoming more restless

Some babies simply sleep better with more space to move. If night wakings increase for no clear reason, the bassinet may be the issue.

4. Your baby is nearing 4–5 months

This is a very common window where babies naturally benefit from more room and a more consistent sleep environment.

👋🏼 If your baby is still sleeping well in the bassinet and hasn’t outgrown it, you don’t need to rush—but once one or more of these signs appear, the crib is usually the better choice.

Room-Sharing vs. Own Room: What’s Best?

The American Academy of Pediatrics recommends room-sharing (without bed-sharing) for at least the first 6 months, ideally up to a year. That said, many families successfully move the crib into the nursery earlier with no negative impact on attachment or safety when done thoughtfully.There is no one-size-fits-all answer. The best choice is the one that supports safe sleep, quality rest, and your family’s well-being.

How to Transition from the Bassinet to the Crib Smoothly

1. Start with naps!

Have your baby take naps in the crib for a few days before making the switch at night. This helps the crib feel familiar and safe and often helps us as parents feel more comfortable as well. Of course, you can go all-in at once, but if that thought is overwhelming, start with naps!

2. Keep everything else the same!

Stick to the same bedtime routine, sleep sack, sound machine, and bedtime timing. Familiar cues help babies adjust quickly.

3. Make the crib sleep-ready!

Use a firm mattress, fitted sheet only, and place your baby on their back. A safe sleep setup builds confidence for both baby and parent.

4. Be consistent!

Once you make the move, try not to bounce back and forth between the bassinet and crib. Consistency helps babies adapt faster.

5. Expect a short adjustment period!

Some babies sleep better immediately. Others may take a few nights to settle in. This is normal—and temporary.

What If Sleep Falls Apart After the Transition?

If sleep suddenly worsens, take a step back and look at the big picture: Is bedtime appropriate for your baby’s age?Are wake windows still working?Is your baby entering a developmental shift (hello, 4-month sleep changes)? Is it time for your baby to learn independent sleep skills? Often, the crib isn’t the real issue—it just happens to coincide with other changes.
