my baby is 1.5 months old. her weight is 3.1 kg and birth weight is 2.8 kg. she is on breastfeed and takes feed regularly, have enough wet diaper. why her weight is not increasing properly.

A. Hello mom babies are expected to gain about 300 g to 1 KG monthly and by the age of 4 to 6 months. They tend to almost double their birth weight. Try taking a healthy and nutritious food or drink, preferably before Baby feed time and that would help in producing a feeling feed and in turn helps in weight gain
