Age gaps between kiddos

So I am 31 and I have a 12 year old son. It was just me and him until he was 9.5 when I met my husband. We’ve been ttc and we’re finally pregnant and doing great so far. ( Had some miscarriages and complications) But I’m wondering what everybody’s age gaps between their kiddos are? Mine will be 13 years.

If you have a huge gap do you worry about them having a bond?
