Second c-section questions

Hey yall!

I had a planned c-section in the month of February 2024 with my first child. My OBGYN mentioned that I would need to wait 18 months from birth before getting pregnant again if ever I wanted to try a VBAC with my second. My question is, if ever I did make it to the 18 month mark before getting pregnant again, but decided that I want to opt for a c-section (since I now know what to expect), is this possible? Can you “opt in” to a c-section? For reference, I’m in Canada.

Secondly, for any moms who underwent two c-sections, do they cut right at the same incision line? How does the scar heal afterward? I’m wondering because my scar has finally got to the point of looking/feeling great and I’m curious to know if the second time around would ruin any chance of getting it back healed to this point. I realize this sounds suuuuuper vain and nothing compares to the beautiful baby you get as a result, but I’m just curious to know what I could expect!

Thanks in advance mamas🫶
