My son is 4 yrs. I am very concerned about his fascination with
horsesHorse chestnut. He likes to line up any books he has with
horsesHorse chestnut in it, then lay them on the floor and look at them all the time. When I ask him what he likes about
horsesHorse chestnut, he says the tails. A couple times I've noticed he got erections while looking at them. I don't want to make him feel embarrassed, or shameful. He is only 4. Is this something I should be worried about? Is this just a faze? Please Help.
