My 23mo DD was doing either 12hr nights, no nap or 10.5hr night, 1hr nap. The last week shes having around 9 1/2-10hr total a day, she's refusing to nap, to go bed, no apop is working, having lots of nw, some long. We have tried meds for teeth but no difference. I think shes got her self so OT that she just can't sleep no matter how exhausted she is. We usually ride OT out and it corrects itself but she seems to be getting less and less sleep with no end in sight. Any ides how to catch her up when she will not sleep?
