I've got a proper belly pillow that suited me well enough with DD. Re food, I generally eat with DD at 6:30 so early enough that it shouldn't be interupting my sleep. I can think of nothing that I have changed (or not changed for that matter) that could be causing this insomnia.

I even tried to have a sleep this afternoon because I was so beat. I slept for 10 minutes and then woke up grrrr. Didn't get back to sleep either.
