Hello :) I recently adopted a pet from my friend (I had to give my baby to a friend to babysit him until I get another pet slot) but I can't use him in battle yet. Is there some kind of wait time until I can use him? I've been training and reading to him every since I got him without any problems.

Yes, there's a 30-day waiting period after adopting a pet before you can use it to battle.

Okay :) I figured there would be a wait time but I wasn't sure ^^ Thank you very much ^^
