3rd child opinion/advice?

I have a 2.5 year old (will be 3 in August), and a 15 month old, born in March ‘19.

My husband and I have both agreed that we want a 3d baby. I just cannot decide when. I am halfway thinking of starting to try now.

I am a teacher, so if the baby was due in March/April, I could take my 6 week leave into the summer while my oldest 2 go to day care and have alone time with the newborn. My oldest will start Pre-K, riding to work with mommy, next August (2021), so I know we could afford day care, simply replacing my oldest’s day care payments with the newborns.

My oldest and youngest (right now) are 18 months apart. If I tried to get pregnant now, my youngest and the newborn would be 24 months apart.
