Hugs, do you think that with your lo dropping her nap, that she may be overtired? What time does she get up for the day, and what time does she go down at night?
My DS 2 1/2) has recently dropped his nap, and will now sleep until nearly 9am in the morning, with going to bed at 7:30pm. He would probably sleep longer if I let him. One morning he slept until 11am after being put down at 7:30. I had been up in the night with our newborn, so enjoyed the peace. But I do know that my DS does get overtired with not napping, although he refuses to nap, he does stay up in his room for 2 hours having quiet time, just reading and laying on the bed.
