I think I know the answer but want to crowdsource my thought...

LO had bad naps yesterday. Which led to a bad night of sleep and a VERY cranky tired baby this morning. And then 2 craptastic naps after that. (Restless and early waking).

I finally (finally!) got her down for a good deep sleeping nap and she's been going for 2 hrs 40 min. I'm inclined to just let her sleep as long as she wants (or like... up to 4 hrs?) so we can break the overtired cycle. But I've never let her sleep more than 3 hrs during the day before so I'm nervous about it messing with night time sleep.

She's 4 mo btw.
