I am a new hcp and just had my dcm tell me this morning that her son, 11 months, had a bite mark on his arm last night. I think my friend's son, 23 months, did it to him yesterday. At one point I was in the next room and he started crying. I thought maybe he was hit with a toy but now I know. I feel horrible and cant stop feeling guilty etc. Any words of advice, etc. Thanks ladies.
