My 6 mo DD was having a really good sleep phase until a few nights ago. For the past few nights she will drop off easily around 7pm then wake around 40mins to an hour later. She's easily settled with boob but then she has started waking again about 10 mins later. Thing is, I'm not sure if she is actually awake, her eyes are closed and she makes an "eh ehhhhhh,ehhhhhh" sound, quite loud. I have been picking her up and rocking her back to sleep but can anyone tell me if this is actual waking or should I be leaving her to settle herself? In general she is showing signs of teething and so I am not sure whether to start being more proactive about teaching her to self settle now or whether I should wait a while. Any thoughts gratefully received!
