sleeping too early!

A

I am pretty sure my 16 week old went to sleep "for the night" at 6 pm but she's still in her day clothes! Leave her? or try to change??she also last ate at 4:15. She started to fuss but I resisted nursing because I feel like that screws my mil over and I assumed she was just tired and needed a nap lol. She's been asleep since a little after 6. I don't want that to be her bedtime! I'll never see her!! 😞
