Fiddle

My son Jordan is a big boy. He was 3.9 kilo at birth and at his 4 month check up was 10.09 kilo.
He is fuly breastfed and we have only started him on solids in the last week.
I wouldnt worry about his weight gain to much. Jordan was putting on a kilo a fortnight at one point.
People always comment on what a big baby he is but I think he is happy and healthy and thats all that matters.
You are doing an excellent job feeding your bubs. I wouldnt be concerned.
