>The fattest baby I've ever seen was completely breastfed.

I, to, have known a couple of huge fully-breastfed babies.  Each was the son
of a mother whe was plump herself.  No 1 little boy had difficulty standing
at twelve months (when still almost fuully-breastfed) because his weight
would pull him over. He looked liked the Michelin Man! Once they started
walking, each fined down considerably.  Baby No 1 turned into quite an elfin
child, and at age 11 he is less than the average weight of his peers.  No 2
could wear clothes at age 3 that he couldn't at age 1 because his thighs
were so fat.  At 8 he now has his mothers large build but carries very
little excess weight.
