DD is doing really well with the transition into her room and I am still working on a schedule/routine but I have a couple of questions?

She always naps in the late afternoon waking not long before her last bottle of the night. I'm trying to do- bath, bottle, book, bed but she seems to wake up after her last bottle when she falls asleep after all her daytime ones. Right now she is content, wide awake, in her crib, in the dark, just fussing when she needs her nuk put back in. How long would YOU let DC "hang out" in their crib? I am so glad she can be content by herself but I feel bad for her but I want her to learn that this is
