My 8.5 month old son has never been a great sleeper (he usually doesn't sleep for more than three hours or so at a time) but he has recently developed a new and very distressing behaviour. He wakes up (usually around 10 or 11pm, but sometimes in the early morning around 4 or 5am) and then screams inconsolably. We have tried lots of different ways of comforting him - cuddling and rocking in our arms, talking softly to him, shushing and patting in the cot etc etc but he continues to scream. He is so hysterical that I can't even get him on the breast (he is breastfed, and is usually comforted by boob). It is not his normal crying - it is a guttural scream. We keep comforting him until he calms enough to go on the breast, after which he will usually go back to sleep.
Some background: he was EBF but is now on three meals of solids per day plus seven or eight breastfeeds. We have a good bedtime routine (dinner, bath, story, breastfeed to sleep) which has been pretty consistent for the past few months. He has never slept very well and still wakes at least twice to feed (usually around 1am and 4am). He also wakes up frequently between 8pm and midnight, but can mostly be comforted pretty quickly. He has just dropped down to two naps (one in the morning and one in the afternoon). I almost always feed him to sleep - he will very occasionally fall asleep in the pram or baby carrier, but if he goes into his cot awake he just crawls around his cot (even in his sleeping bag!). During the day he is a very happy and contented baby - most of our friends and family have never seen him cry. He did suffer from reflux when he was younger but he has grown out of it (and this screaming is different from the reflux and trapped burp crying he used to do).
We are finding this very distressing, and are desperate for some advice. We are not bothered by the waking up (which is not unusual for him) but by the fact that he seems to be in so much distress
. Crying it out is not an option for us (and he just gets more hysterical if we don't intervene immediately anyway). Does anyone have any advice / experience with this?
