Don´t worry, it is very normal for nosy aunties to ask these details. If you start bothering about it and it shows, they won´t go easy on you.
Just stay friendly and funny with a bit of sarcasm, like: ´Abhi to me khud bachi hu´ or I already have a baby, BIG baby ( point at your husband)´.
And what worked for a friend of mine:´Bas duaa karen....(smile) ´.
Bas duaa karte kartey us ne at least 3 years guzar diye....
Aunties will be annoying and nosy!
I remember one aunty saying: ´Agli baar aap 2 nehi 3 aana´.........
yeah "bus dua karain"always wors best.if u gonna tell them u don't want one right away they'll b more curiou n bother u more.or instead of saying u r not ready say"mera tu buhat dil hai bus ye abhi nahi mantay"but do take ur hubby in trust b4 putting the whole blame on him, lol
