Oh honey, I hope D is ok. Seems like the calpol is what he needed though.
Thanks for all the sympathy. I don't think I was quite clear though - C tolerates being put down while awake, for up to 20mins on mat or in chair. What she can't manage is day sleeping without me. I have many days where I sit on my bed with a sleeping baby on me, for hours at a time. If I put her down to continue her sleep she wakes within minutes. It's just so boring. If I do put her down, to wee or get food etc, my reward is a grumpy baby who I have to help back to sleep anyway. It's not short bursts of crying I can't manage, it's a baby who hasn't slept and is a nightmare.
Today was better though - we took her in pram to Borough market and she mostly slept while we were walking. She even stayed! asleep! when we stopped in a restaurant on the way home, so we had a drink and a snack. 20 mins of her being asleep and me being sat down not holding her was sheer heaven.
As for other suggestions, my husband would happily take her so I could go out, but I don't really have any girlfriends here I could go out with - they either have their own babies, or health issues. I don't have any family here, or anyone who doesn't work full-time. It's tough.
