hi doctor i am a very worried mom, at first my baby was growing very well from the birth weight of 2,7 because at three months she was 4,4, during those times she had a flu and it seem like her life was not goin well, took her to the docter and he just said if she is playfull the is nothing to worry about, every month she has flu and now she is 9 months and only weighs 6,5kg
