My girl is 8 months today, and for the past couple of weeks, it's been hell getting her to take a nap or sleep. She has one tooth that's already come in. I don't see any others. Once she show signs of sleepiness, I immediately breastfeed her (which has worked out really well in the past). She'll start to close her eyes, but then, for whatever reason, she'll start fighting sleep. She'll blow raspberries, pull on my shirt, toss around, and then start fussing. I've tried putting her in the crib for a nap, laying her on my lap, rocking her, pacifier, sound machine, dim lights...nothing works. I've also started putting her to bed earlier, like around 8 pm. She wakes up nearly once every hour now. I am exhausted and frustrated. Any thoughts?
