Michelle, thanks for the advice. I've been trying to feed more often which seems to be helping. He seems more satisfied after his feed now. I think he's having a bit of a growth spurt because I saw a friend last night who we haven't seen for two weeks and she was fairly suprised by how much he had grown in such a short time. I think tonight I will put my pump/bottle beside the bed so that its ready to go in the morning.
