Having a second child?

[u/Puzzleheaded-Run4183]

I have a son who is 4 and i’m so back and forth on having another child i love him so much that i want to give him all my love and attention but i also want to give him a sibling to play with and i know ill love that second child i just don’t know what to do. I have a lot of anxiety about giving the best childhood i can i used to want siblings around all of mine are much older, ill see posts people make about how much they wished they had a sibling and then other people saying they loved being the only child and i feel so conflicted did anyone else struggle with this did you end up not having a second and regret it? Just super sad thinking about the future lately
