Dear M.,
At 22 you are not going to be an old mom if you wait to have another child until you finish school and get married. You don't say how old your little one is; but how close to have children is very individual.
This I can tell you with confidence; you will enjoy your children a lot more if you finish school (enjoy the fun times that go along with being in college) then enjoy planning a wedding and getting married. If you do, when you have your next baby you will have time and and have experienced enough of life to be able to really enjoy your precious little ones.
I have adopted 11 children and loved many more whom I cared for in foster care. My youngest child is 8 and five are still at home. I love being a Mom. In fact, I have done many other exciting things (nurse, hospital administrator, college professor, high school teacher to name a few) but the role I enjoy and appreciate the most is that of being a Mom to the most wonderful and exciting people I know.
I would encourage you to give yourself time. Enjoy the little one you have already and enjoy this time of your life without rushing to get to the next or do them (life stages) all at once.
Warm regards,
S.
