Put babies asleep in the bassinet when they are awake.

First, try putting your baby in the bassinet while they’re still awake. It will help them get used to its feel and sound. You can also try gently rocking the bassinet or singing to your baby until they fall asleep. You can always put them back in their crib for a nap if all else fails. 

Shorter naps 

If your baby is still not sleeping in their bassinet, you can try putting them down for small naps during the day, so they are more likely to be tired at night. Parents must also consider that an overtired newborn baby can get fussy sometimes.

Check the bassinet for comfort.

Is the bassinet comfortable for your baby? Sometimes newborn babies won’t sleep in their bassinets because they are not pleased. If this is the case, try adding soft blankets or pillows to make it more comfortable. You can also try raising the mattress so your baby is slightly elevated.

Make sure the bassinet is the right size for your baby and that there are no sharp edges that could hurt your baby. Moreover, the baby’s bassinet must be in a safe, quiet place where your baby can’t be disturbed. 

Swaddle your baby

Swaddling can help calm and soothe an overtired baby, which may help them fall asleep in their bassinet. While swaddling, remove the baby’s head from the blanket and wrap it around the baby’s body. If you’re unsure how to swaddle, read the complete guide on how to use swaddleme swaddle.

Use a white noise machine.

Try a different bassinet.

If your baby still won’t sleep in their bassinet, it might be time to try a different type of bassinet. Some babies prefer co-sleepers or Moses baskets, so it’s worth considering these options if nothing else works.

Talk to your pediatrician.

You must talk to your pediatrician if you still have trouble getting your baby to sleep in their bassinet. They can offer additional advice and help you rule out any underlying medical conditions that could be causing the problem.

If your baby is still refusing to sleep in the bassinet despite all these efforts, you might consider a new sleeping arrangement. Some parents find their baby sleeps better in a swing or bouncy seat. Others find that their baby sleeps better in their arms.
