Oh I've had that before! Thinking I'll get her up now as she's been playing around for 30 mins, to find she's asleep! Little monkey!
APOP doesn't work here, I just send myself loopy. I just think as long as I give her the opportunity to catch up on missed sleep then at least I've done everything I can iykwim? Luckily most of the time my LO tacks on some lost sleep with EBT but that doesn't work for everyone either. I guess it's just trial and error to find out what works for you and your LO.
Hope the night went well.
