My baby is 4 month old and her weight is 5.89 is this correct weight for 4 month baby. And she her poop is always of green colour she is on formula milk

A. Since your child is on formula milk green colour and grey colour would be very common to be seen so that is not a problem and depending upon what was the birth weight of your child you have to evaluate it should be minimum 2 kg more than the weight or more than two so if your child has gained that kind of weight then that is very healthy
