Is it too early?

ShaQuee • I jst want to be the best that i can be..
Currently I am 19 Y/O with a 4 year old son. My SO and I would like to start TTC after my 20th birthday this summer. Everyone is telling us to wait it out, but by the time I have my next child, my son will be 5. I understand that I am young, and by no means am I in a rush to have another child, but I really don't want my children to be so far apart in age. Plus I have baby fever like crazy
