Babysitting vs having your own

Bailey
I am a full time nanny to a 16 month old and a 5 month old. I love kids and my husband and I are are TTC. The kids that I am a nanny for are so sweet but when they wipe their nose on me or projectile vomit I can't help but think "EWWWW!" Will that change with my own baby or will I always think "EWWWW!"? I just feel like I will be a bad mom if I think it's gross when I have poop, snot or God knows what else on me but it's always been someone else's kids....HELP! 😭
