My fiance` and I are planning for our 2nd pregnancy..

I know the exact planning to a T won't happen,but my fiance` wants our second child to be born around my mother and I's birthday. My mother and I are 20 years and 1 day apart on our birthdays. I personally don't care when our second bundle of joy will be born as long as the baby is healthy like our current 6 month old son. Any tips or suggestions?
