Is it normal for a newborn baby to sleep for more than 18 hours?

Hello,

Welcome to icliniq.com.

It is an absolutely normal behavior of a newborn. They may sleep even twenty to twenty-two hours per day. Nothing to worry. As the baby grows, the duration of sleep decreases accordingly. So, keep your baby warm and feed every second hourly.

Thank you and have a nice day.

Hi,

Keeping warm means covering the baby properly and not exposing to cold surrounding like directly putting the baby under fan or AC. If the baby is not warm, it may develop some issues like not feeding well, dullness, etc.

Thank you and have a nice day.
