I'm worried because my baby sleeps 10hrs to 12 hrs in one stretch and doesn't pee during this time. Not passing urine more than 6 to 8 hrs. please help also his morning diaper has this colour

A. I see not passing during while sleeping it’s a natural bladder control and that’s very normal and otherwise your child is active giving sufficient amount of weight is not a problem in the diaper also seems fine but if you want you can check with your doctor
