If I hear a random scream when the kids are seemingly playing together happily, it is often because both boys were pushing around this toy (below), Adam tripped & fell, and Matthew kept going, somehow mowing over Adam in the process. Adam will either be underneath the toy, or crawling after is as fast and furiously as his four little limbs will move him.
This evening, though, was different. As I was putting the boys to bed, I gave Matthew his sippy cup, which Adam promptly swiped and took for himself. Nonplussed, I just gave Matthew the other sippy cup, which Adam swiftly stole as well. Sighing, I took the first sippy cup that Adam had discarded and gave that cup to Matthew. Quickly, Adam took that cup as well! This went on 5-10 times.
