Our 11 week old was a nightmare today and didn't nap much. Only an hour and a half. She usually gets between 4 and 6 hours during the day and sleeps 7.30 pm to 7 ish am at night. But after a screaming match due to overtiredness that started at around 3 pm, I eventually got her to sleep at 5 pm. She's still asleep now and it's 7.30 pm. not sure what to do - wake her and keep her awake for a bit or let her sleep and hope she sleeps through the night? What would you do?
