My 7 month old is such an independent little mama, it kind of makes me sad. She crawls and pulls herself up on things already so she basically just goes, gets what she wants, and plays. She doesn't really want or need me for entertainment. I feel awful because my first wasn't like this, and I just wonder if my second is because she hasn't gotten all of the one-on-one time her sister got... mom guilt is eating away at me. Having 2 kids is so much harder emotionally than I expected.
