Bruises on baby. 😰

My son just started walking and he likes to chase the cats. He was after one of them earlier and ran under the table and hit one of the legs. He fell and now there's a big bruise across his cheek and on his leg. He has his 12 months well-check in 2 days and I'm horrified they're going to think I've beaten him. πŸ˜” Will they listen to me if I explain or automatically call CPS? I feel ridiculous. The poor thing looks like he's been in a car accident or something.Β
