My LO is just shy of turning 16 months and has been waking up just once every single night for the past month. She used to sleep great. Sometimes it takes 20 min to get her back down sometimes it takes an hour and a half. This is so frustrating to me because I know she can sleep through the night. Is it a leap? I don’t think it’s teething as I feel no molars coming in. We’ve been on one nap for 2 months now almost 3 months. My next step is maybe an earlier bed time. I think we may be keeping her up too long to make it to bedtime. Anyone have any advice? Anyone else’s LO doing the same?
