My baby is 27 days old and he is not gaining weight .At the time of birth he was 3.2 kg but now he looks like 2.5 kg .What is the problem ,why he is not gaining weight?

A. actually I see your baby is newborn with the very first month you can not expect any kind of weight gain usually the baby will lose in the weight in the very first month and also it completed depends on the food intake whatever you think because it comes in the form of breast milk to baby
