What I miss most about pre-dad life

Money without guilt. Before if I wanted to buy some new tech or go on a random weekend trip I just did it. Now I think about 529 plans and school costs and it stresses me out. I miss my body not being wrecked. I miss sleeping 8 hours straight. I miss my wife looking at me like a partner instead of her co-parent and backup plan. I miss being selfish honestly. None of this makes me regret having kids but I'd be lying if I said there aren't nights I miss being 28 with zero responsibilities.
