Quoting ShesAbstrakt:" Can toddlers have Obsessive-compulsive disorder or maybe she is just really particular, lol. My daughter ... [snip!] ... 3 and didn't like dirty things. He doesn't have any other issues at 22 Lol. I don't think its a big deal just a bit different. "
My son I think is OCD. He is 3 but ever since he was eating solid food at 6 months he would spill and ask for a napkin or paper towel and he would wipe it.
Now he doesnt like food on his shirt, won't use a toilet if it's dirty, and wants his face and hands washed right away.
