My 3.5 year old son has been toilet trained from age 2 with no issues or resistance. He had a bout of constipation with bleeding a few months ago. When he had the bleeding episode he was very upset and I tried to be reassuring without making a big deal out of it (he tends toward the dramatic). Now he always wants me with him when he goes #2 saying he's afraid he'll have more blood. I've gone with him thinking it would resolve itself if I was matter of fact and didn't make a big deal out of it but it's been at least 3 months now. Any suggestions?
