The alternative scenario here. I planned to have kids four years apart and ended up with them being five years apart. This spacing allowed me to breastfeed both for a year, enjoy the baby years of each and even remember them, finish my dissertation and have the older one to attend the commencement ceremony

Knowing myself, I would be overwhelmed by two little ones at the same time and would feel guilty for not spending enough time with them. Not saying you would, though.
