Don’t give a shit what other people think. I went through puking etc. in transport and public places. Just focus on kid comfort and prepare yourself with bags, wet wipes and backup clothes.
Holly shit, I did PCI IVRs! We were quite paranoid, like you can quess card number by side channel attacks like timings. It’s very niche, but fun part of tech world. PCI audits, security, HSMs, etc. Anyway, I never give my CC number 😆
