Lea - he looks fine to me!!!!!! He might be just a "big boy" and that is normal for him. I wouldn't worry too much about what other people think, can't expect to please everyone!!!! I always have people pick Aricyn up and go.. woahhh.. he's so heavy... and he's just under 10kgs at nearly 12 months. He's been this weight for a few months now, but I don't see a problem with it? I don't see a problem with a 14 month old being 12 kilos, as long as he is getting around and not suffering for it and is a "normal" little boy (normal for him, not to anyone else's standards) I wouldn't be too concerned. Go with your gut. Do what you think is right for him, not right for anyone else. :-)
