How to negotiate with a 3 year old and win!!

Miss N. has a teddy which she carries around with her EVERYWHERE.  Teddy is a bit worse for the wear but Miss N. loves him.  When dd was doing Miss P's  8 month photos, she asked Miss N. if she wanted to have her photo taken?  She said no, but teddy wanted his taken.

Below with Miss N. is Annabelle.  Annabelle was given to me Christmas 1967, so she will be 50 years old this coming Christmas.  At the same time I was given a pram to put her in.  It turned out I preferred the sit on tractor of the neighbour boy and he loved my doll and pram?

 Miss N. has taken a shine to Annabelle and carts her around with her when she is at our house.  She wanted to take Annabelle home with her.  I said fine but then I keep teddy...........

 Annabelle is still with us, and teddy went home with Miss N!  Just in case you're wondering, teddy loves to eat Shepherd's Pie and uses the toilet just like Miss N!
