I'm a (mostly) stay at home dad - I hope it's OK to post on mumsnet. :)
DS is 19 months, still breastfeeds (evenings, nights and weekends only!) and cosleeps. He's not the best of sleepers, usually waking three or four times a night, but he usually just grumbles enough for his mother to notice, latches on and drops off.
The last three or four nights, he's dropped off to sleep fine but woken up pretty much every 45 minutes or so (i.e., every sleep cycle - occasionally he lasts two) crying his seriously-upset cry. He's needed anywhere between five minutes and half an hour of soothing each time before he'll drop off again, sometimes with worsening crying, sometimes just calming down when cuddled and sung to.
He seems to be napping OK (an hour and a half this afternoon - he stirred after forty five minutes, but settled with just a touch on the back to let him know that Daddy was still there). He doesn't seem to be in any discomfort, doesn't seem to be hungry or thirsty. He doesn't seem to be waking mid-cycle and seems peaceful when asleep, so I don't think it's nightmares, and he's definitely awake, so it's not night terrors. I read that ear infections can cause nighttime crying, but he seems fine during the day, no cold-like symptoms or anything (we're planning to go and see the doc tomorrow just in case).
He seems to be handling it fine - he's his usual self during the day - but his parents are becoming a tiny bit grumpy. Does anyone have any advice?
