Hi fellow mumsnetters. I feel I'm at the end of my tether tonight. My youngest child, who Is 9 months old, has not had a full night sleep since he was born. My first baby was a total angel and slept through from 3 months. I've literally tried everything. I probably haven't, but at this point it sure does feel like it. We can't let him cry it out like we did with our first as he shares a room with his brother and 1 child awake all night is enough. He does have a dummy, but I don't really want to take that away as it's the only thing that (occassionally) does put him back to sleep. I mean on a good day he still wakes up 3-4 times a night. Sometimes it's literally just rolling him over and putting his dummy back in, but the last few weeks has ended in me having to get up with him anywhere between 3 and 5 and taking him on the sofa. I've spent the last hour with him, fed him a bottle, gave him some calpol (cos he's got a tooth through), changed his bum, but he just won't sleep. I spent the while time crying as I just don't know what I'm doing wrong. He doesn't nap hardly at all during the day so I know it's not that. Any help or advice at this point would be brilliant. From one sleep deprived, on the edge of a break down, mummy of 2 boys xx
