DD is 21 months, and for the past few days she’s been doing something weird. She’ll lie on her stomach, and tuck her hands under her, and it looks like her body stiffens. She’ll stay like that for a while, and I have no idea what’s going on. The past 2 mornings when I woke her up, she did the same thing, and then flipped out when I took her out of her crib. She’ll throw a tantrum for a while, but then she’s over it. First I thought maybe she had a tummy ache, or was having a seizure, but that doesn’t seem to be it. I can’t figure it out! Anyone have any ideas what could be going on? Maybe it’s nothing?
