No, laughing is good. But she did the right thing you know. By not reacting, he realizes he isn't going to get anything out of the fit. He'll have less fits as a toddler if she keeps it up. Also, dont have her give him "fresh" bread. It can be choked on pretty easily, even in small amounts. This is just because its so soft and gets sticky when wet. Have her toast the bread first. He wont know the difference and it's safer.
