Is it all right for the baby to lie long?

It's generally not advisable for a baby to lie flat for extended periods, as it can lead to issues like flat head syndrome (positional plagiocephaly) and hinder their motor development. Babies should have supervised tummy time while awake to strengthen their muscles and promote healthy development. Additionally, it's important to change their position regularly to ensure comfort and prevent any physical concerns. Always consult a pediatrician for personalized guidance.
