Any suggestions please- dd is b/f and I'm exhausted, also have a nearly 2 year old ds. She has a feed first thing (I try and make this around 7am but she doesn't always want it until later as she's fed in the night) then 11am followed by a little bit of solids then 2.30pm feed, 5pm solids (I have to fetch ds from nursery and deal with him when I get home so can't do her feed plus solids at the same time) then feed around 6.45pm after her bath. She sleeps well in the day - has a nap in the morning, a long lunchtime nap and a short nap late afternoon around 4ish so she has between 3 and 4 hours sleep a day. She's a very variable feeder, sometimes wants a little (just one side) and sometimes a good long feed. We've tried leaving her to cry in the night (I don't leave her at the first feed as I think she needs that one as I don't give her a 10pm feed as I have to go to bed before that and also she doesn't wake up enough to feed) but she just won't settle without boob in the night. What am I doing wrong?
