Haven't read the whole thread - waaaaay too long!! but can I join?
DS2 is 18 wks ( I think, keep losing track due to sleep deprivation) and was up at 9.30, 1.30, 3.30, 4.30, and 5.30 last night - yawn.
He's never been great - we've had a few nights when he's only woken once between 10.30 pm and 7 am, but they're in the minority, generally it's twice, but sometimes more than this.
He can self settle himself to sleep, as long as he's swaddled, which is fab, and he's generally a very quick feeder who goes straight back to sleep once he's done, so it hasn't been too killing.
Last night though, he was crying and unsettled a few times in the night, which is really unlike him now - he was like it A LOT in the early days though - but he's had a rosy cheek today and has also been pulling at his ear.
So he may be teething or have an ear infection, not sure. I've given him Calpol and he's gone off ok so far, so we'll see what the night brings.......
My sympathies to everyone having a rough time at the moment - it's grim isn't it, esp if you're working or have other kids to look after. But we shall not be beaten.........!
