Idk if it’s the 18 mo sleep regression or teething or what. But LO woke up at like 2am and didn’t go back to sleep till 5am! At first cried, brought to our bed, and then tried breastfeeding and tossing and turning. Then just happily babbling to herself and being wide awake. Anyone had this happen? What did you do? Do you let them sleep in or make up the time difference of sleep in their nap?
