my baby is a really light sleeper. We have to share a room w her 4 now, and when I lie her down, 1/2 the time, she wakes up! Also, when I climb into bed, she wakes! I think it's the rustling of the blanket. I am already using my least noisy blanket! We already play music to drown out the background noise. Any ideas on how to get and keeep light sleepers asleep?
