Age gap with having ONLY TWO kids

My daughter is 6 months old. I only plan on having one more baby, a total of two kids. Because I only want two kids, I don’t want them to be too far apart in age but I don’t want it to be too close. I was thinking of TTC # 2 in October (daughter will be 13 months) and I know pregnancy may not happen *right* away..not too worried about that though.. so if I were to get pregnant around then my two kids will be almost two years apart or two + if it takes a little longer. Do you think this is a good/reasonable gap? I just don’t want them to be so far apart in age or wait too long but I don’t want those two ages to be too hard to raise together.
