TTC #2 too soon?

Little background!
Im 23 married for 3 years and have a one year old! We're currently kind of trying for #2 already! I really want my son to have a sibling that's not too much younger! I was an only child and it was boring! I always wished I had a sibling and I have a half sister that's 20 years older than me lol so my question is am I crazy for wanting another baby so soon? :) let me know how close your kids are in age & how is it?
He needs a buddy!! vvvvv lol ❤️
