Miss B - your little man sounds like a perfectly normal 2 year old boy! I'd love to hear if the paed says anything different, but that all sounds pretty normal to me.

DarkDreamer - your DD sounds EXACTLY like my son was at that age, and we kept being told it's just normal newborn behaviour... finally someone decided to look into it further and the poor darling was suffering from Silent Reflux. A bit of medication and he was 100 times better... less crying, less arching of his back, less grumpiness in general. I genuinely think that if we had worked it out earlier his first 3 months of life would have been so much easier for all of us - so definitely get it checked out and if you feel something isn't right, make sure someone listens to you.
