1 and half old baby not gaining weight but breastfeeding 2 to 3 hours once and urine output also normal 14 to 15 times.what is the reason for not gaining weight? please reply me

A. The urine output is good which means that the child is consuming good amount of milk still if the weight gain is not happening then maybe it’s not healthy enough for weight gain in that case I can only suggest you to start giving formula feeding to the child
