Jilly, do not keep the rest of the kittens. There are many loving homes for them and you will find them good homes. Yes they are adorable, and yes, you have grown attached but you have to do what is best for them and you in the long run.
Ask your self these questions before you decide to keep them. Do I have enough money for food, spaying, kitty litter, kitty shots, vet bills, etc? Do I have enough time for all the kittens?
It is very normal to feel sad when you place them in homes and they leave but put your big girl pants on and do the right thing for them and you.
You do not want to be the lady that everyone calls the "crazy cat lady" in town!!! lol
