2 1/2 years apart ....

Hey all, i am pregnant now due December 29th with my 2nd baby, i have a daughter now she’s 2 years old ... and i seem to get a lot of backlash from my mom saying oh your having them to close in age and you can’t handle it and your not ready. She always trying to down me!

But I’m trying to figure out how they too close in age but my brother and i are Aren’t even 2 years apart my brother is November ‘90 and my brother birthday is January ‘89

Anyway my question is if you have more then one child how far apart are they?
