No problem here for Oliver I suspect as he was a good weight when he was born, as was Lucy, though girls seem unaffected according to this study.
On the other hand I was premature and only weighed around 5 and half pounds, subsequently dropping much lower before rallying after my Dad apparently gave the nurses a hard time about the sloppy feeding routines.
Oliver is eating lots of apples at the moment. Breakfast often starts with one. He often asks for an apple in preference to asking for a sweet or chocloate. Perhaps that's because he enjoys them or perhaps it's because he knows we will always give him fruit when he asks, whereas ice-creams and sweets have a more limited supply.
