my baby is 2 month old and he is not gaining weight what should I do?

A. Hello mom a full term baby is almost expected to gain between the range of 300 gm to 1 kg and then by the age of 4 to 6 months of age they almost double their birth weight.you need to take a healthy filling nutritious diet preferably before baby feed time as that would ensure good quality feed and which is filling enough and would help in weight gain .
