Hi,
I know this thread is quite old. But I just wanted to say that a bit of acting out and hitting isn’t uncommon in toddlers so it is very unlikely that she has picked up your OCD – especially since you have already been working on it. As other posters have said, it can pass on either through genetics or mimicking behaviour so just take it as a reminder to look after yourself and get as healthy as possible for your family. I know that is far easier said than done. But remember, no parent is perfect, we can all only do our best.
