2 under 2 with a 3 yr old

Hi everyone,

I have a 3yr old boy and a 6 month old girl. I just found out I’m pregnant with my third that’s due next year march.

Ngl the 2 under 2 age gap kind of scares me, but I honestly want to be as prepared mentally as I can for this. If anyone has been in this situation has any tips, tricks or stories (good or bad)please share.

Thank you so much.
