Hi My 13 Year Old Son Just Came To Me

hi my 13 year old son just came to me upset. He said it's happened a few times already. When he moved his bowels this afternoon when he got home from school there was a little blood when he wiped. He said he went again 2 hours later and still a little blood. I told him to not worry about it and to start drinking more water or apple juice. I asked him if he strained to release and he said yes.
