Michelle, with Zara, I introduced it at a very very young age, so what I did probably wouldn't apply. However, now that Emily is older, you could make 1 particular toy, of your choosing, a part of your day - lets take xxx to brush his teeth too, lets take xxx to get watch while you do this or that, bring xxx to teh dinner table, oh, when we feel sad, giving xxx a cuddle helps us feel better (you will obviously still have to cuddle to in the beginning). XXX is your friend, he can sit in your cot and watch you sleep blah blah blah.
If she likes your hair (Hugh likes mine too) then try a doll that has hair, even if you have to buy a new one. Or try a my little pony, the hair on the tail and mane often is an ok substitute for Hugh.
HTH, and that night you had sounds like it is going alright to me!
