Re: Returning to work, how to get baby to nap with Grandma??
One thing you could do is have your mother come over and help with naps a few times while you're still home. She could see your routine and see what she could use -- for example, if you read a book before nap, she could do that. With my LO, she wore a little sleep sack (still does!) so putting that on and turning on her sound machine was a cue for her that she'd be going to sleep for whomever was there (our nanny or my husband usually). She could hold your LO until he falls asleep, which would probably be similar enough to being cuddled during nursing to help fall asleep.
