Thanks for all your help!
My LO has a comfort item, a bunny rabbit/blankie and she holds it every night but she wants that and the dummy in the night!
When we've sat with her and put our hands on her to comfort when she's crying she picks up our hands, pulls them about, puts them in her mouth, scratches etc.....! I've sat there for 45mins before and she was no more asleep at the end as she was at the beginning!
With regards to our routine, I'm always slightly confused how to approach it because she wakes up so early. Today she stirred at 4.50am but we didn't actually go into her until 6.15, I know that she was chatting to herself a lot during this period but I fell asleep so am not sure whether she did as well. I usually count 3 hrs from waking up before first nap but if I'm unsure of when she finally woke for the day this is tricky. She doesn't have any obvious tired signs apart from being v grumpy and that's when she's over tired. Also, I was told to never wake a sleeping baby and as her nights are disrupted I always leave her to sleep during the day - maybe I shouldn't? We haven't done an early bedtime and to be honest I'm terrified of it in case she wakes even earlier. She went down straight away at 7 last night which was half an hour earlier than the day before.....but then she woke half an hour earlier as well!
Sometimes in the night though she really doesn't seem like she's massively tired. Hmmmmmph, who knows what to do....
