Well done you! I can also say that BFing can make your baby chub chub chubby, mine doubled his weight at around 2 months old and has now more than quadrupled his birth weight at 10 months! (he was only 5lb 10 BTW in case you think I am carting around a 40 pounder just now LOL)
My DH went on an all milk diet in his twenties in an attempt to lose weight and gained half a stone in two weeks. I always dust that anecdote off when people wondered if milk was 'still enough' for my dd pre-weaning.
