Pula - thanks for your fantastically detailed reply! A lot to think about, thanks.
We tried (and keep trying!) a dummy, but despite much persistance she just spits it out all the time. Yes to keeping a hand on her. I think it is partly startling herself awake, I should try swaddling more often - although I'm not very good, she usually fights her way out of the blanket...actually, does anyone use a swaddle 'product' rather than just a regular blanket? I can't seem to BF her to a deep sleep - she'll doze off but very lightly and wake very very easily, no matter how long I sit still with her, that's why I fall asleep every night holding her. I'm sure we'll get there eventually, but atm I'm sloghtly embarassed to admit that I'm not really sure what her natural patterns are, it seems to change every day.
Right, I'll stop this wallowing in self pity about the lack of sleep. I've survived it before and will again. I just thought that because DD1 was so bad I might have earned a good sleeper this time!!
DD1 has been really funny today - she's started breast feeding her doll! She's also started doing some role playing games, where she gets an imaginary muslin, puts it over her shoulder, winds the doll, gives it a bath and so on. I'm sure those of you who have older children have seen this before, but we were amazed at how elaborate it all was, and how long it all went on for.
chocbunnies - I'm sure you'll be fine with two. I was terrified the first time, but we survived...just! Top tip - get out of the house, even just for a walk. I really don't think I could have stayed in all day.
