Thanks everyone (again). ❤️ March has definitely not gotten off to the best start. Sorry I've been such a moaner about it all. I'm ever more in awe of you ladies doing this with one or more other children underfoot. No idea how you cope.
Anyway, after a couple more failed attempts at the cot, I got Alice's Moses basket back out. Still took 2 attempts to settle her in it, but at least she did sleep. The next feed, she went into her cot. I think she was so tired, whatever causes her to wake up wasn't enough to force her out of sleep. The feed after that, I put her back into her basket. Partly because I needed more sleep, and it seems the basket is more of a guarantee. And partly because if she was in the room, and didn't sleep, DH could damn well get up to wrangle her for a bit.
Going to keep persevering with the cot. Just going to believe this sleeping blip is the result of her illness and won't be long term.
@Horehound Is your HV happy about his weight gain? If they are, I wouldn't be overly worried.
There's such enormous disparity between baby weights. One of my NCT group baby's was heavier at birth than Alice was at 5 weeks old. I think it was a few weeks more before she reached his birth weight! At baby groups, you'd never be able to tell Alice was one of the oldest babies there if you just went by size.
