There's always going to be someone who disagrees with your parenting style. My fiance already has trouble with his mom, because whenever his daughter goes over THERE she is allowed to do things that she wouldn't be allowed to do if he were there - for instance, she doesn't care HOW much TV she watches, but Cody doesn't want her to be watching TV when it's nice outside or when she could be doing something more productive or creative or whatever. They had a HUGE issue with this last week, and it made Cody so mad that his mom even argued with him on it in front of his daughter at all. (He has a hard enough time showing his daughter that HE is in charge anyway...)
And her friend seems to think that pacifiers are the devil, and ANYTIME she sees a child with a pacifier or I talk about pacifiers or somebody else brings up pacifiers, she starts telling them off and saying how horrible they are and saying it's just bad parenting - when really, it's just a personal choice. Her I have learned to ignore. My MIL though, it's hard to argue with because I really do like her a lot and she DID raise my honey to my liking XD.
I try not to argue with anyone on parenting topics though, except cody, because I know it can be a sensitive subject for ANYONE who has raised a child.
Fact is though, I'm going to raise my child how I'm going to raise my child, and that's that.
