Make an appointment?

My 2 year old took a fall down our back stairs about 2 weeks ago, he just got a bruise on his face from the fall. But my mother has noticed his walk has changed. He has a little limp & his foot goes outwards when he walks. Now that I think about it, he never walked like that. Should I make an appointment to get his leg checked out? I hope it’s not too late if something is wrong 🥺

** Update: he was & has been playing fine. He runs & jumps fine. It’s just the little limp & outward foot we’ve noticed! He hasn’t complained about anything hurting. (He knows how to tell me if he has a booboo) Which is why we didn’t think to take him in sooner.
