Thanks for your encouragement! As far as diet goes, there's nothing new, in fact I've recently cut most dairy from her diet, so I would think that's not it. She did gave a tooth cut recently, but this has been going on for about a month now. She's never been able to put herself to sleep, but we did BW training before & that helped us wean nught feedings, night wakings, cosleeping, nursing to sleep & actually got her to take naps! But we have never gotten to the point where we could just lay her down & she'd go to sleep.
