Food fight

Something very strange is happening in this house. My beloved off-spring has withdrawn her affection for real food and now has little to no interest in eating. She had done so well with solids during the first week that she was eating them but then her first tooth popped up and she wanted nothing to do with food. I keep trying to feed her and sometimes she'll take a small amount of whatever I'm offering but mostly, she just wants to nurse. I'm assuming that this is just another phase that she'll grow out of but it did make me mildly concerned for a few days. However, I realized that it was fairly unlikely that she would continue to only sustain herself using breast milk and I'm just trying to not worry about it.
