@brandnewcoffee WOW, why do people think it's OK to be so rude? 
When I became pregnant (25+ years ago,) I actually had a couple of extended family members (a generation or more older than me,) laughing, and saying 'I can't wait to see YOU with a baby. You won't know which end the nappy goes on!'
I was nearly 30, married, in a professional career, and had my own home (with DH,) but apparently I wouldn't know which end of the baby the nappy went on.
A few similar comments ensued before my baby was born! 
Hilariously, the people saying this had (teen and young adult) children who were rogues, thugs, and generally pretty unpleasant people, so THEIR parenting skills were questionable. 
Obviously projecting, and just being a cunt.
FTR, Esme is a cute name, so ignore your nan.
