Clairey - not sure how you can stop your ds, but in my opinion just the fact that you are seen trying to do something about it gets my vote. I can't stand it when mums leave their little horrors to do whatever they want without intervening, usually they are too busy gossiping and having a coffee. By the way, your dd does sound amazing for her age - counting to 10 at 19 months? Are you and your dh very clever too?
BT - I feel your pain too, this is a difficult stage and most of the time I am around people with older, self-sufficient children or babies who don't move. I don't think people remember or realise how much hard work it is when they are so mobile, but too young to have any sense of danger or responsibilty. I had dd2 on a canal boat last week for about an hour. It was not a fun hour!!! However I know it will get better as I have dd1 - I can't wait for the day they can both go off and play, leaving me to sit and gossip and drink coffee (see above)....
Wizz - another vote for Baa Baa blinds, they are DEFINITELY worth buying. They are quite expensive but you can use them forever, and take them away with you. We take them wherever we go - when we were in the Isle of Wight the children's room had black-out blinds already so we used them in our room! However on the early waking, I'm afraid I just thing this is quite normal at this time of year, I remember dd1 used to wake up about 5.30am all through the summer when she was a toddler. We just used to take it in turns to get up with her. Now we consider it a lay-in if we get to 6.30am with neither of them having woken (in fact I still sometimes check they are still alive if they sleep until 7am!)
Sorry to hear about sickness, sounds awful, hope you're feeling better.
