my baby is 7m old. her bones sometimes make crackling sound while sudden movements as we observe in knees in old aged people. is it ok ?

A. It’s completely normal as the bones are growing up now you know the kids do not have proper bones when they take birth as the age progress is the bones are going to take it shape and you know their progressing with their size and also which is why you can hear little bit of sound like cut cut that’s completely normal
