My 8.5 month old has never slept through the night, and I feel like we've never quite got over the four month sleep regression - but now we've hit the eight month one and everything's even worse! He has already now (at 10.55) woken up four times since going to sleep at 7.50. On a good night he can do a six hour stretch (though hasn't for weeks now), on a bad one it's hourly wake ups. The problem is that even on nights where he only wakes two or three times we often get periods of an hour plus where he won't be settled back to sleep and he just screams while we walk round with him OR (better but somehow more frustrating?!) he is happy but awake and will lie grinning at us in the cot but cries when we leave the room. He has also been reliably waking up at 5am for a few weeks now and although he's clearly still tired nothing will convince him to go back to sleep.
I gave up breastfeeding him at night when I went back to work at 6 months which at the time seemed like a way of getting through because DH could do most of the nightwakings (he's been on shared parental leave but is going back in a few weeks) but in hindsight just took away the most reliable way of resettling him.
We've tried everything we can from all the 'no cry' stuff, to no avail. Cosleeping works really badly for us - I basically don't sleep at all and he's a restless nightmare and we still have to get up to resettle him when he wakes - but we have been resorting to it recently because although we still don't sleep at least he isn't screaming (he is giggling, crawling over us, slapping me in the face and pulling DH's hair, though).
When he was six months I got as far as booking a sleep consultant and then cancelled because I felt too guilty. I've got in touch with her again but still feel conflicted. She's a 'gentle' sleep consultant but did warn that with the method (basically gradual retreat) there are tears. Part of me is scared that there's actually something wrong and we'll be letting him cry when he's in pain - he does have mild eczema which doesn't seem to bother him at night but I worry that maybe he has an undiagnosed allergy or something (we haven't been able to track his skin to his food at all). On the other hand he seems so tired so much of the time that I wonder how many favours the current situation is doing him. I'm also really underperforming at work and my flexible arrangements are based on me working in the evening at home a few days a week, which I'm really struggling with.
Any thoughts? Advice? People who have done it and regret it? People who have done it and think we should go for it?
