Hi today my baby has 1 month completed and baby weight .2kg 200gm but his body is still thin please help to increase body

A. Hello mom babies are expected to gain between the range of 300 gm to 1 kg monthly and by the age of 4 to 6 months they almost double their birth weight. If he is on your feed then you have to take care of your diet and prefer to have nutritious food or drink preferably before baby feed time as that would ensure good quality milk and help in weight gain
