Visiting from March DDC, but my Mom swears that getting up in the middle of the night when you are pregnant makes the baby wake up at those same times to eat.
I just laughed at her, but by the end of my pregnancy with DS, I was getting up 3 times a night. And he was up at those same times to feed every night for at least the first 6 months (2am, 4am, and 6am).
So this time I'm doing what my Mom did for her second pregnancy. Trying not to drink so much before bed so I don't have to get up and trying not to get up if I wake up! It worked for her - I'm #2 and I slept great from the beginning!
Some people seem to handle the baby/sleep thing all right, but it was miserable, torture for me. I'll hop up and down and spin in circles if I think it might help!
