my baby is 1 month old , he sleep all day quietly.but at night he always make sound in like stretching...i don't understand why he make it

A. But if the child is not crying while making the sound of stretching then it is completely alright because their body also needs to stretch itself because they’ve been in a very small place the body is very clubbed at this time when they’re into your womb which is why they behaved like this which is normal
