It's really strange as it used to be daytime that he was uncomfortable and his naps were disrupted, but his night sleep was good. Then he went on Ranitidine and days quickly got better, but nights didn't improve, even though I keep him upright for a good while after a feed and have his cot propped up (do have a wedge but found it was too severe an incline). His reflux symptoms have disappeared with taking Ranitidine and being held totally or semi upright during and after feeds, so my constant debate with myself is how much of this is emotional / behavioural and how much is reflux.
Basically what happens is:
At night seems to sleep very lightly for some of the time - wriggles around a lot, easily disturbed. Particularly after his first night feed, even if he is held upright for a good while afterwards.
Wakes up an hour pretty much to the minute after he goes to sleep at night.
Keeps waking up, often every 90 minutes; sometimes more often, sometimes he can go for longer.
It's not hunger - he can go for quite a while without needing a feed, and he doesn't seem uncomfortable or upset. He just keeps waking up.
This period of bad night sleep started when we did a trip away from home 4 weeks ago, which was also the time he seemed to be having a growth spurt. Coincidentally his reflux got worse the day our trip started (at home, so it wasn't triggered by the trip).
So... it's really hard for me to know what's causing this - i.e. reflux or emotional? I've been treating it as reflux but I'm not convinced that's the issue as his reflux does seem broadly under control, he's sleeping pretty well during the day, and he's still sleeping like this at night. Plus if I put him in bed with me - on the rare occasions I relent - he sleeps a lot better.
I've only just started trying to get him to settle at night and day as far as possible in his cot (which is working), and if this is an emotional issue I know persisting with this should help. BUT if it is reflux, then that's really hard to do because of the keeping-upright issue - it's often unavoidable that he falls asleep on me after a feed.
At a real loss, and totally exhausted...
