My mother did that but not like that. She didn't let us taking straight from her mouth. I never did that with my kids cause I thought it was gross. But as long as the child isn't hurt I don't see the problem, let her do what she do. Everyone does things differently

That is what baby food is for! I don't think it is wrong for her to "feed" her baby that way,but it is odd.

I really do not know what to say about that.... it looks gross to me but to each their own I guess....
