Vix - nothing works exept sleep training for C, but last time he was this restless, he was coming up with an illness!! So as Julz said, if you think it might be SOMETHING other than wanting mommy...
VIx, most of us have had to do proper sleep training like the first time. If you respond with a bottle or a snuggle, that is what he will expect and if you go in after 10 minutes or 20, thats how long he will cry to wait for you to come in again! Cam was also waking 3 - 4 times a night and I WAS A WRECK!! ( and i am not even preggies) and after the sleep training, he slept through after 2 long nights of crying. but only you know if its just him trying his luck or if you think there is something really wrong that you cant figure out.. good luck and keep us posted. Try not to give him a bottle as thats what he expects now

He just doenst need it.. The nutritionist we heard at a workshop said that EVEN if they dont eat supper, it wont kill them to go without milk through ONE night.. otherwise you could open up a can of worms with night waking " FOR THE ROADHOUSE TAKEWAY" they get at midnight..
