It seems like Baby Audrey was taken away from her cat-mommie too soon, because she sucks on my tummeh all the time as if I was her cat-mommie! I do not mind at all when she does it. In fact I will let her do it for hours. It comforts and calms me too for some reason. It is the only time Audrey purrs verreh, VERREH loudly, and the only time I realleh sit still and be quiet myself. I generally hold her head or snuggle her body while she does this, to let her know it is okay with me. My mommeh was dumbfounded at first, and I will admit it may be a little bit odd, but by now we have all come to terms with it because it does not look like we will be able to get her to stop doing it. The only thing is that she is no longer teensy, and by now she has big sharp teeths. Sometimes if she bites me too hard, or when I have just had enough, I bunnykick her in the head to make her go away.
I suppose it is not most gentle or motherly way to ask her to stop, but at least she always gets the message.
