My DD has never been a good sleeper, 4 month sleep regression was horrendous, but a few weeks ago, at about 8 and a half months she started going 7-6. Bliss. Until a day after she turned 9 months and now it's horrendous again. I can cope with her being up/awake but I just wanted to check if anyone else finds their baby cries/screams as they go through this? This happened at 4 months too. She has had Calpol / Calprofen to rule out teething but for the last 2 hours she has been screaming on and off and rolling around madly in her cot. Last time I went in she had her bum in the air mid-crawling motion. She is trying to crawl / pull up and cruise during the day. Have I got this to look forward to every night until she achieves it?
