My cat has empty womb syndrome as soon as each litter is out of hers...
I have a cute little fainting goat that likes to cuddle.
Oh, and 4 new puppies!
I wish we could babysit my neice, she's in the age you're talking about, and I can so relate. I sometimes mourn that husband and I probably won't have another child because of the difficult child's. Its more than just that, tho, its the possiblity of "normal" that I long for as much as the child itseld.
Hope you can find a cuddler soon.
