Aiden's been in his own room since 10 weeks but one of us sleeps in there too. I know it's harder for you as you haven't got your OH sharing the nights - I really don't know what I'd do if I wasn't getting a sleep every other night! I've decided to wind up the breastfeeding after the weekend as he's just not satisfied anymore. We've been combination feeding since 6 weeks and he settles much better after a bottle feed. Ah, the dreaded 4 month sleep regression - I hope Harper settles down for you soon!!
