DS will be 4 months this week. For the last few nights he has been waking me up several times due to sudden outbursts of moaning/groaning. I assume he’s awake but his eyes are shut and he’s still actually asleep. Luckily he doesn’t wake and settles back down but he’s doing it half hourly(ish) and it’s waking me up every time, I’m grateful that he isn’t actually awake but I’m getting a bit tired! He’s had his fist in his mouth a lot lately, sometimes in an agitated way, and dribbling. Could it be teething related or perhaps 4 months sleep regression? He has been generally quite cranky too.
