Sledg - Thanks for the link to that other thread. I can really relate to the feeling of having lost a whole year. Pretty much every day I feel appalled at some aspect of my own behaviour. I once heard that children don't remember anything that happened before they were four and I've been clinging on to that thought (only a few months left though) but I know it's probably rubbish. But I hate the thought of my dd remembering me as the kind of parent I've been in the past six months or so.
I'm also finding that the experience with my spirited one has made me not want to have any more kids. I love the idea of a big family but, on top of the general exhaustion of everything being such a big deal with dd, I no longer have any confidence in my parenting abilities.

Vanessa - Good idea, thanks.
kittn - I suspect she is pretty sensitive but it mostly seems to be about touch. She seems to feel pain strongly and has trouble with textures, labels etc. She is also extremely hot/cold sensitive... always one or the other - never just comfortable. She's fine with food. Noise sensitivity is a bit of an issue, but nothing too major.
It's interesting that you mentioned 'tight hugs' because I actually tried that today when she was thrashing about and crying and it worked after about 15 seconds. I just scooped her up and took her to a quiet room and used all my strength to just hold/hug her really tight. She calmed down so fast it was amazing. I'll be trying that one again, that's for sure.
