First time mum mistake 😭

I always clean my 2 years old child’s ears with just washcloth and water when I give him a bath but today I noticed buildup of wax and I made the most stupidest mistake ever... I used a Q-tip to try to clean the ear. It was AFTER doing this that I went online to search on google for how to clean a child’s ear and I read a lot saying never to use q-tip. I immediately started crying! How stupid could I have been!!! I feel so horrible, I feel so bad! What if my stupid mistake causes damage to the ear?! I can’t even go to bed now because I keep thinking about it
