Am I silly for wanting another baby?

My daughter is 11 1/2 months. Turns 1 on November 1. I always said I wanted my second child years after my first. Like 4-6 years after. But now that I have my daughter, I regret saying that. I miss her being so tiny! Plus, I selfishly kind of want to have my kids now so that I can raise them now together instead of them being so far apart. I think what makes me feel weird about this is that my boyfriend and I are only 22. We bought a house together though and have been together for two years. We see a future with each other. I just guess I am seeking second opinions on if it's normal to have baby fever right now or if I should just wait?
