Does anyone have one of these? Do you find it to be effective? my DD is 3 and just switched to a big girl bed. she stays in it til we get her, which is great - but she yells from her bed "is it morning?!" over and over and over until we get her up. not only is this exhausting (she's up at 530-6) but the baby's room is between my room and my 3 year old's..so she ends up waking her up too.

help?!
