DD1 takes after her dad, she's was skinny from the start. Everyone on his side of the family have crazy metabolisms and are incapable of gaining weight no matter what they eat.
DD2 on the other hand was not a big chunky roly poly baby (just average) but it a huge difference to her sister. They are now 2 and 4 and get mistaken for twins (despite the height difference) all the time. DD2 although shorter is a bit wider than her sister.
Both were exclusively breastfed for a year.
