Should I swaddle my newborn at night?
Yes, you should swaddle your newborn at night. The startle reflex is a primitive reflex that is present and birth and is a protective mechanism. With any sudden noise or movement, your baby is “startled” and her arms will extend away from her body, she’ll arch her back and neck.
Is it OK to swaddle a newborn all day?
Keep your baby un-swaddled during waking hours
Keeping your baby swaddled all of the time can hinder motor development and mobility, as well as limit her opportunity to use and explore her hands when awake. After the first month of life, try swaddling your baby only during naps and nighttime sleeping.
Can my newborn sleep in a onesie?
In warm weather over 75 degrees (3), a single layer, such as a cotton onesie and diaper, is enough for a baby to sleep in. In temperatures under 75 degrees, additional layers are necessary. Breathable newborn baby pajamas made from materials such as cotton or muslin can be used along with a sleep sack.
