My 5 week old has fed constantly for the last couple of days. I put him in his cot at 7pm last night to deal with my big ones, woke him at 9 to try and feed, woke him at 11 for a bottle of ebm then he fed at 315 and I tried to feed him at 6 where he took half a feed I had to express the rest and now he is still sleeping. He hasn't been properly awake in over 13 hours. I am not complaining but it's very out of character.
