Be prepared for it to sink in in a few weeks. Oscar was amazing for the first three weeks and then it hit him that this was for life - he became very, very angry, rebelled against everything - giving him a shot or a finger poke became a half hour ordeal - he kept saying he was never going to eat again and was just going to die (all very upsetting). It took about a month before he settled down and started to accept it again. I hope this doesn't happen but if it does, it's just the next stage and completely normal. Just be patient and understanding.
