I’m the worst mom ever for giving my baby mcdonalds

I feel so guilty. We work on vacation and didn’t get home until 10 pm last night so we stopped and got McDonald’s. Our daughter is 1 and has obviously never had it. We got home and I gave her little pieces of a chicken nugget and like 5 or 6 fries. She then wakes up in the middle of night around 2 am ( she sleeps with us ) just tossing and turning. Then by 3 sits up and starts throwing up and is crying and choking on it and holding on to me so tight. I was literally crying it broke my heart. It was all McDonald’s she threw up. I will never give her that again then she threw up agai 45 minutes later. Today she’s better and acting fine but It was so sad and I should have been smarter
