We are pseudo-nap training right now and I think it's going fairly well all things considered. The biggest issue is that while she used to be able to sleep 1.5-2 hours in her swing, that stopped working, and now that she's in her crib she wakes up really cranky at the 40 minute mark.
A few times I have been able to run in when she first stirs, pick her up gently & rock her back to sleep for 10 minutes. Then she takes a monster nap! And wakes up super happy. I'm glad to keep doing this as much as I can, but I'm hoping she will eventually start taking longer naps on her own?
