We are just back from holiday and picked up our 11 month old boy today. He looks absolutely huuuge! I am sure there is an element of not seeing him for 2 weeks and your mind playing tricks on you. Also there were 3 stray kittens in the hotel that we were staying at in Corfu that the kids fed that were very very tiny (and obviously malnourished) so I expected him to look big in comparison.
But putting all that aside he does seem like he's chunked out quite a bit. He has come back with a fair bit of the food that I provided so I know they haven't been over-feeding him. So could it purely be down to lack of exercise for 2 weeks? Would that have an affect so quickly?
