personally feeling personal stories are valid is such discussions as this. This research may very well be accurate for the sample of children they observed and researched. But what is happening in real life to ordinary children out there right now IS important too.
Hmmm, not my experience but there you go.
DD was breastfed for 4 weeks, then bottle fed entirely from 6 weeks. She was also weaned early. She is now 4 and has NEVER gone through a fat or chubby stage at all. She is a very active little girl and always has been. She adores her food but we follow the everything in moderation rule of thought.
I was breastfed but was always had a bit of "puppy fat" and big cheeks with dimples, right until puberty. My brother was formula fed, due to medical reasons, and has always been pretty skinny. My sister was breastfed and was skinny on the whole too.
Dh was bottle fed and was always a tall, skinny thing. His brother was also bottle fed but was a chubby little thing.
Just thinking of the children I know at them moment, where I know a bit of their feeding/weaning information, and there appears in my small selection to be no correlation at all It is all very varied and mixed TBH.
