Okay, my kittens are now just over eight weeks old, and i still sometimes catch them nursing on mommy. it looks funny, because she is a tiny cat and the kittens are huge compared to her. it is not all the time and usually when they all cuddle together to go to sleep. should i be discouraging this or just let them decide when enough is enough. I am keeping them all until they are twelve weeks old. It drives my husband crazy seeing them still nurse,
