As concisely as possible (LO is 17 weeks now):

Until 13 weeks LO was an amazing rockstar sleeper. STTN, 3-4 one or two hr naps/day. Set her down awake but drowsy an she slept in 5 min.

Then she needed to be rocked to sleep.

Then she started getting up 1-2 times/night

Then she started getting up 4-10 times/night

Then she started whining/crying at nap/bed time when we tried to rock her to sleep (but if you set her down she cries harder) but would usually set in 5-10 min.

All thats fine... sounds pretty typical 4 mo regression from what Ive heard.

But-- LO has been super drooly since 5 weeks but the last week has been INSANE. Like keep a bib on her 24/7 or her shirt is soaked in 10 min. Also she's liked chewing on things for a few weeks but the last week she like, GNAWS really hard on everything. And she sort of whines while she does it, but then cries if you take it away. She's been a bit fussier than normal while awake. Then she gets tired (clear tired signals, rubbing eyes/yawning like she's always done) and when I try to put her to sleep she sobs. She doesn't want to eat (she eats right before naps, which is compounding this problem), she doesn't want her binky. She chomps chomps and tries to chew on her paci or the bottle but not suck, and then she gets angry and screaaaaaams. And I can't always get her settled anymore. The last two days she's had only 2 naps (rather than normal 4) and has wound up overtired and somewhat inconsolable. It's so sad. Once she's asleep she sleeps for a long time as long as you watch her-- at around 30-45 min after she falls asleep she stirs and you have to replace her binky or rock her back to sleep then she sleeps 1.5-2hrs.

So something is definitely going on and it doesn't feel like JUST 4mo regression anymore bc of all the chewing and the SOBBING instead of just fussing at bed time. Thoughts?
