i ve had so many nightmares with kids, but the best was when i was on a transatlantic flight and was sat right next to a teething baby who didnt stop screaming all flight and his mom made it super awkward by breastfeeding him in front of me, and right before we were getting ready to land the little bugger managed to thrown up all that mommy milk on me lol
although for guys i feel its a matter of time i have a friend who has a girl now, you should've seen him prior to marriage he was talking non stop on how he hates babies and how he hopes he gets a boy as he thinks its easier to raise up now his daughter is all he talks about if we ever see him!!
