My little girl is 3 months old and she weighs 7 kilograms! She was born 4035 kilograms so she too is a chubby bubby. She is breastfed and my health nurse said that breastfed babies normally put on weight quickly and then it evens out.

Good on you for keeping up with the breastfeeding. It was hard at first for me also but I am so glad it has worked out in the end!
