Can't really help you Cat - Blake is similar - BF or a slight bounce/rock thing to sleep at night for the first sleep, after that (3hrly STILL; 4hrs is a bonus) wakes and will really only settle with a BF. So I get where you're coming from. Been meaning to finish sorting out the possibilities from the No-cry Sleep solution by Elizabeth Pantley for night time sleeps (had started to sort it out to do this, was intending to do something during the school holidays but Blake's been sick so haven't wanted to upset him too much). He also used to do the 30-45 min sleep x1 day and that was it. I really didn't like those nights = more wakeups. Eventually he's grown out of the only 30-45 min sleep once a day and is now averaging a 1 - 1 1/2 hour sleep during the day. Now just have to work on the night time sleeps

I ended up taking a drive (10 -20min) and Blake would end up sleeping for over an hour in the car when I got home in the driveway (with me there too). Swimming lessons helped a bit too (did this Saturday mornings) as it tired him out, we had some beautifully long sleeps in the car after that. I think that's helped him settle into the longer day sleeps a bit which has meant slightly longer night sleeps before waking up (we were averaging 2hrly there for a while - not fun while back at school full time especially as Tim can't BF for me at night and I really only have enough bottles of EBM for the next day)

Not sure about ideas with the separation anxiety thing - Blake's always been quite social - handed around to everyone from early on and childcare from about 4mths so haven't really had to deal with that one. But he does love his BF when I get home after school - can't do anything till that's been had
