He looks huge on the middle picture but I think its how he was laying, with the arm of the sofa lifting his legs. Roughly what age do they stop growing?
@Fregie2012 I think they grow up their first year and then widen out a bit more at 2-3 years old! When we adopted Gio at 20 months he was tall and lanky and was about 48lbs, he kept getting wider and probably stopped filling out last fall at 2 and a half, he is now 58lbs!
