I was wondering if anyone else has a baby with cmpa who does not sleep well. My 8 month old still wakes at 10, 1, 3 and 5 or 6. He wakes to feed but won't drink much milk. Before he was put on prescription milk he would sometimes be up all night so things have improved but I am still finding it tough going. I have read that there is a link between cmpa and sleep problems so was wondering if anyone else has experienced it and if there are anyway to improve things?
