as the title suggests, I think we are currently going through the notorious 4 month sleep regression. Although a tricky start, my beautiful ds slept 6 to 8 hrs from 2 months until 3 and a half months. I couldn't believe it! Of course that has come crashing down since 3 half months, and his nights have become increasingly worse! On a good night he wakes two to three times, which I could happily live with, no problem. But on a bad night, like last night, he doesn't go down until 9pm, wakes hourly, and last night wouldn't sleep from 1am to 5.30am! Historically when he wakes he goes back to sleep easily, but not the last week! I'm so exhausted and he must be too! I do try and sleep when he naps (touch wood - this is still ok) but I'm not the best napper either, and stress makes it worse! From what I hear this is quite common at 4 months but I wanted to hear how others coped. I would love to co-sleep but ds is not a fan, he's non-committal with a dummy, hates the pram and car! Aarghh! Someone give me hope!
