My baby girl is 2 years 8 months now. She played with a cancer patient who completed his chemo treatment. He age is 35 and done with his treatment just 15 days before. While they were playing my baby accidentally bite his hand and tried to bite on his shaved head.. i tried to stop but she did it very fast that I couldn't stop her at that time.. but her bite was not that hard enough .. Now i started thinking whether it will affect my baby by doing like that? Is it ok ? Do i have to take any precautions?
