My little girl is 15 weeks old and had started sleeping amazingly 7 or 8 hrs stints followed by 3 or 4 hours a few weeks ago. The last few days we’re back on waking every 2 hours all night..I’m guessing 4mth sleep regression.
During the day she has three naps..two that last 45 mins and one that lasts 3 - 4 hours. Do I need to wake her during the long nap as she’s now sleeping longer in the day than at night?
