​

Things to Do For Your Baby

  • Learn what normal behavior is for your baby and what causes your baby to be stressed.

  • Learn the cues that your baby gives you when he/she is ready to interact. These are called "I'm Ready" Behaviors.

  • Discover the type of touch that soothes and comforts your baby.

  • Learn how to lay your baby in comfortable positions.

  • Learn how to keep your baby tucked in the fetal position. This means bringing your baby’s legs and arms close to his/her stomach and chest.

  • Learn how to nest your baby in the isolette. This is called containment/ cradling. It is done by loosely wrapping your baby in a blanket and placing rolls completely around his/her body. This gives your baby boundaries on all sides and helps him/her stay in a tucked position.

  • Position your baby’s hands up close to his/her mouth or face whenever possible.

  • Support your baby’s head while holding.

  • Hold your baby wrapped in a blanket or skin-to-skin (kangaroo care). This is when mom or dad holds the baby on their chest, with the baby’s skin next to theirs.

  • Touch your baby with a firm caress rather than soft stroking movements.

  • Have the nurse instruct you on bathing techniques for your baby.

  • Once your baby can open his/her eyes, allow him/her quiet time to just focus. Babies have a hard time handling several things going on at a time, such as talking, looking around and being touched. Your baby can become very tired just trying to focus on you or an object.

  • Shield your baby’s eyes from bright lights.

  • If possible have your baby look at your face.

  • Bring in a blanket or afghan from home to cover your baby’s incubator. Your baby needs to be in a dark environment when sleeping and have periods of light during awake times.

  • Talk or read to your baby in a low quiet voice for short periods of time.

  • Offer a pacifier during tube feedings if you notice your baby making sucking movements.

  • Your baby needs sleep in order to grow.

  • Use only one form of interaction at a time with your baby, like speaking softly, rocking, or touching.
