I hate that feeling I get when I'm around people that don't know what's it's like to have kids and my daughter throws a huge fit. I don't know why but it just makes me feel like I'm a bad mom. It was time to put jammies on and get ready for bed and my daughter was refusing and I wasn't taking no for an answer so I ended up taking her away screaming and kicking. Now I know she doesn't throw huge fits like that on the regular and we did a lot today with no nap so I know she was over-tired. I just don't know why I get a little insecure when she acts up around people that don't understand what's it's like to deal with children.
