Dear everyone,
I'm at my witts end. I don't know what to do. My baby Ollie hasn't slept a stretch of more than 4 hours since birth...he is now 7 months old. I've tried it all, earlier bedtimes, cry-it-out, "tanking him up" before bed, nursing, not nursing, longer naps, consoling him, pick up/put down, shush pat. I've tried going in his crib with him in the middle of the night (as Tracy Hogg described in her book with the little girl that was scared of her crib...he just screamed....)
This morning I just wanted to shake him (of course I didn't do that) for the lack of my own sleep.
Here is our situation and PLEASE give me some feedback.
He was exclusively breastfed until 5 months old and I would wake up in the middle of the night every 1 to 2 hours from the age of 4 months to 5 months to breastfeed him (and 3 hour intervals from birth until 4 months).
At 5 months, we started solids. So I decided to try and give him cereal before bedtime to see if he would sleep longer. Didn't work..did that for about a week. Now he eats about half a cup of cereal 2 tbsp of some vegetables and nurses before bed (but I put him to bed awake at around 7-8PM and he falls asleep after fussing for 5 minutes or less). We have a bedtime routine and it works to put him to sleep at 7-8pm...its the middle of the night that is the problem. So I tried to take out some night feedings...well, that didn't work since I haven't fed him overnight in nearly a month now and he just screams and screams and screams.
He falls asleep easily for naps and he'll sleep 1-2 hours in the morning and once in the afternoon...I try to keep his nap time at the same time every day (9AM and 2-3 PM)
So the problem is that, he falls asleep very easily when I put him down wide awake at 7 to 8PM for the night but its the 11PM, 1AM, 3AM, and 4AM then 5AM waking and crying for 45 minutes that stumps me. I just dont know what to do. When I nursed him back to sleep about a month or so ago but he would wake up again 2 hours later... if I don't nurse him, he just cries himself back to sleep (or screams in my arms or screams while trying the pu/pd or stops screaming for half a second with shushpat and then starts screaming again) for 45 minutes only to wake up again an hour later.
My son got his first teeth at 3.5 month. Today, at 7 months, he has 6 or more teeth (4 on top and 2 bottom). Could it be teething that has kept him up? I've tried baby tylenol, but still didnt do much for his sleep.
I dont know what to do! My patience is running thin... I haven't slept a span of longer than 4 hours without waking since he was born.... ugh.

We are going on vacation next week and we will be in a hotel room. I can't imagine only sleeping 3 hours every night because I can't shut his room door. and I'm sure our routine will be disrupted....but we havent made any improvements anyway...
HELP! Any suggestions and ideas? I'm desperate.
