my daughter's birth weight was 2 kg and she is 3.5month old weight is 4.6 kg since last week she doesn't gain any weight..any problem??there is no health issue to her right now.

A. Hello mom as she is not having any health issues now would rather suggest not to worry , babies are expected to almost monthly gain within the range 300 Gm to 1 kg and then. By the age 4 to 6 months they would almost double their birth weight
