Age Gap Between Kids

If you have more than once kid, what is the age gap between your children, or, what do you think the ideal age gap is?

I’m pregnant with my second son and my boys will be 2 years 8 months apart, and I’m worried that the age gap is too big and they won’t be close.

The vast majority of my friends and family have kids that are 2 years apart or closer so I feel like this age gap is too big.

What do my other mamas think?
