still nursing?

My Kitts are now 9 weeks old and still nursing. They must still be getting milk cause they are licking their chops when finished. The problem is momma seems to be annoyed with the whole nursing thing at this point . Will they just stop or is there a process that needs to take place on my part. The babies have been eating food for about 4 weeks

she'll stop them when shes ready. just make sure your feeding her kitten food so she has enough nutrients to keep her healthy.

as the kittens are 9 weeks old most vets will spay her now which will discourage the kittens from feeding off her.
