Yes, she sleeps on a wedge (she slept 10hrs straight the first night she had it!) I have had her cot raised on books too, but she just kept sliding down the bed!
I'm not sure if she has reflux or not. Her symptoms seem to come & go, which would suggest to me she doesn't(?) I do winder if she's just eating too much! I'm seeing her reflux-friendly GP again in a couple of weeks, we've tried gaviscon in the past, but it didn't help. I'm going to ask if there's anything else we can try.
