The bassinet is a perfect first bed for a newborn. It is small, cosy, and close to the parents bed, which makes night feeds and checks much easier. But babies grow quickly, and there comes a point when the bassinet is no longer the right place to sleep. Moving to a crib is a normal part of growing up, and with a little preparation it can go smoothly for the whole family.
Many parents worry that the move will disturb their baby sleep, and it is true that some babies take a few nights to settle in a bigger bed. The crib feels different, with more space and a different view. But babies are adaptable, and most adjust within a week or two when the change is handled gently. This guide explains when to make the move, how to prepare, and what to do if the first nights are unsettled.
When to Move Your Baby From Bassinet to Crib
There is no single age that suits every baby, but most move to a crib between three and six months. The most important factor is size and development, not the calendar. Check the weight and length limits printed on your bassinet, and move your baby before they reach them. A baby who can roll over, push up on their hands, or sit up should be moved as soon as possible, because a bassinet is not designed for a baby who can move around.
Other signs can help you decide. If your baby looks cramped in the bassinet, wakes when they bump into the sides, or seems restless in a small space, they may be ready for more room. Some parents choose to move their baby when they start sleeping for longer stretches at night, since the crib is a good place to build a lasting sleep routine. Others move when the baby outgrows the bassinet but still sleeps in the parents room.
- Your baby is near the bassinet weight or length limit
- Your baby can roll over, push up, or sit up
- Your baby looks cramped or wakes by bumping the sides
- Your baby is sleeping longer stretches at night
There is no need to rush the move if your baby is still comfortable and safe in the bassinet. But do not wait until the bassinet becomes unsafe. Making the change a little early, while your baby is settled and well, is easier than making it in a hurry after your baby has already outgrown the bed.
Preparing the Crib for a Comfortable First Night
Preparation makes the transition much easier. Set up the crib in advance, in the place where your baby will sleep, so it is ready before the first night. Use a firm, flat mattress that fits snugly, with a fitted sheet only. Keep the crib empty of pillows, blankets, bumpers, and soft toys, since these are not safe for a sleeping baby. A sleep sack or wearable blanket is a safer way to keep your baby warm.
Make the crib feel familiar by using the same sheet or sleep sack your baby already knows, if you can. The smell of home is comforting to a baby, so a sheet that has been washed in your usual detergent can help. Place the crib in a room that is cool, dark, and quiet, with a temperature that feels comfortable to you in light clothing.
A Gradual Plan for the Bassinet to Crib Transition
A gradual plan works well for most families. Start by moving the crib into your room, if that is where your baby sleeps, so the only change is the bed itself. Keep the bedtime routine exactly the same, with the same bath, story, song, or feed in the same order. Familiar routines tell your baby that it is time to sleep, even when the bed is new.
- Keep the bedtime routine the same every night
- Start with naps in the crib before moving nights
- Place your baby in the crib drowsy but awake
- Stay close for the first nights if your baby needs you
- Give the new setup at least a week before changing it again
On the first night, place your baby in the crib when they are drowsy but still awake, so they learn to fall asleep in the new bed. Stay nearby for a few minutes, with a gentle hand on their chest or a soft voice, until they settle. If your baby cries, comfort them calmly and try again. Most babies need a few nights to accept the change, and that is normal.
If your baby is moving to their own room at the same time, consider doing the two changes separately. Move to the crib in your room first, and move to their own room a few weeks later once the crib feels familiar. Changing one thing at a time is gentler and helps you work out which change caused any waking.
Handling Waking and Unsettled Nights
Some waking in the first nights is normal and does not mean the transition has failed. Your baby is adjusting to more space, new sounds, and a different view. Give the new setup at least a week before deciding it is not working. Many babies settle by the third or fourth night, and a week is a fair test for most.
When your baby wakes at night, respond in the same calm way you always do. Check whether they are hungry, need a nappy change, or are too hot or cold. Keep the room dark and your voice low, and avoid turning the waking into playtime. A short, calm response helps your baby learn that night is for sleeping, even in a new bed.
Avoid moving your baby back to the bassinet after one hard night. Going back and forth can confuse your baby and stretch the transition out for weeks. Consistency matters more than perfection. If the nights are very hard, it is fine to take a short break and try again in a week or two, but once you restart, stay with the crib.
Safe Sleep Habits for the Crib
Safety in the crib follows the same rules as safety in the bassinet. Always place your baby on their back to sleep, on a firm flat surface, with nothing loose in the crib. The room should be free of smoke, and the temperature should be comfortable, not too warm. Overheating is a risk, so dress your baby in light layers and check the back of the neck, which should feel warm but not sweaty.
Check the crib itself for safety before the first night. The slats should be close enough together that your baby head cannot fit through, the mattress should fit snugly with no gaps at the edges, and there should be no loose screws, peeling paint, or broken parts. If you are using a secondhand crib, check that it meets current safety standards and has all its original parts. Our guide to safe sleep rules every parent should follow covers these points in more detail.
Helping Your Baby Feel at Home in the Crib
Moving from bassinet to crib is a milestone, not a test. Most babies adjust within a week when the change is gradual, the routine stays the same, and the crib is safe and comfortable. Start with naps, keep bedtime familiar, and give your baby time to learn that the bigger bed is a good place to sleep. For help with the wider sleep picture, our newborn sleep schedule by age shows how sleep changes as your baby grows. With patience and consistency, the crib will soon feel like home.
What age should a baby move from bassinet to crib?
Most babies move to a crib between three and six months, but size and development matter more than age. Move your baby before they reach the bassinet weight or length limit, and as soon as they can roll over, push up, or sit up.
How long does the bassinet to crib transition take?
Most babies adjust within a week, often by the third or fourth night. Give the new setup at least a week before deciding it is not working. Consistency helps, so avoid moving your baby back to the bassinet after one hard night.
Should I move the crib into my room first?
Yes, keeping the crib in your room at first makes the change gentler, because the only new thing is the bed itself. Once your baby is settled in the crib, you can move it to their own room a few weeks later if that is your plan.
What should be in the crib for safe sleep?
A firm flat mattress with a fitted sheet is all a crib needs. Keep pillows, blankets, bumpers, and soft toys out of the crib. A sleep sack or wearable blanket is a safer way to keep your baby warm through the night.
