A child throwing up because he is in the presence of food he doesn't want to eat, just does not seem normal to me. i would want him to be seen by a doctor before returning to care. Obviously he really misses mom too and it's playing a huge role in all this, but actually throwing up just because of food would really worry me. Gah I feel bad for parents sometimes who are stressed and overworked but it angers me too because the kids pay for it dearly!
