TTC again?

I have an almost 2 year old.. and gave birth a year ago to a precious baby boy that was born without an esophagus. (VERY RARE) and unknown cause..

Doctors say it’s not genetic & chances of it happening again are slim to none. They think it was because I got pregnant just 2 months after my 1st was born and my body wasn’t ready

Since it’s been a full year is it still frowned upon to try again so soon?

We just want a big close in age family...

no negative comments plz.
