Popping in from WTTC because I'm always so curious to know how others have dealt with the age gap. Hope you don't mind me sharing my experience
How old was your first born when the second baby arrived (and so on)?
Cohen was 20 months
How did he/she adjust?
Better than me or DH

He loves this baby so much and is so protective of him. Here is a pic of him the day we brought Abram home. He is crying because I am taking the baby out of his lap so I could feed him.

How did you adjust?
I had a hard time adjusting to the new dynamics the first month, but Abe has been a very difficult baby w/ allergies & reflux and I never dealt w/ those things w/ Cohen.
Your husband?
He's been great and always has been. He works and isn't around the baby all day like I am so the constant fussiness didn't wear him down like it did w/ me.
Do you like the age gap? Any pluses or minuses?
LOVE it. Cohen was able to help get diapers and clothes, stuff like that since day 1. Now Cohen is in full blown terrible twos and I dread thinking what life would be like w/ a newborn at this time

. We hope to have another w/ the same age gap.
