4. Dress Your Kid Appropriately

Before you dress him/her, understand the temperature of the room. Make sure to put them on a long sleeve shirt, thick pajamas, socks, and others. 

NB: it’s not always recommended to put socks on the baby before sleep. Especially if the room temperature is okay. However, a tip for you is – #socks are sometimes helpful for a baby with a fever. 

5. Use Tight, Fitted Flannel Sheet

Before getting into this segment a suggestion is to use a firm mattress in the crib instead of a plush mattress. 

Now to keep the mattress warm, tight, fitted flannel sheets are found efficient. However, make sure it’s bunched up. Because it can increase the risk of suffocation by covering the baby’s mouth and nose. 

6. Swaddle the Baby

Do you want to know how to keep baby warm in crib without blankets? If so then the last tip for you is to swaddle your kid. Swaddling helps to maintain body heat. So, babies can sleep with comfort.

Can your baby roll onto her stomach? Then the previous suggestion of swaddling is a big NO due to the risk of suffocation. In that case, a sleep sack is a safer option for your kid. There is no chance of suffocation and it provides plenty of legroom for the babies. 

Sleep sacks are founded to be effective in keeping baby warm in the crab, however, there’s a condition; the sleep sack must be made of breathable and warm material. Nested Bean Zen Sack is one of the recommended sleep sacks for your baby (6-15 months).


Even though all the methods are safe and easy to do, there is still something you should keep in mind. Below I’m addressing the points.

  • Never cover your kid using any loose blanket. It increases the risk of suffocation.
  • Whatever method you try to follow, make sure you aren’t making the crib too hot for the baby. Overheating the baby results in serious health risks.
