What I usually just tell people is that the Canadian Pediatric Society and the World Health Organization now recommend a minimum of 2 years of breastfeeding. Quite a mouthful, but usually people don't know quite what to say to that, they wouldn't argue with a doctor, would they? I also state my breastfeeding goal which is to nurse DS for a minimum of 2 years. This was my personal goal before I knew of the CPS and WHO's recommendations. I state it clearly and confidently and I think if I have confidence and respect in myself that shows others something too.
Incidentally, I got lots of questions when DS was around 9 months-1 year b/c this is the time when alot of babies stop nursing. Haven't got so many questions recently.
Your husband thinks weaning your baby will help your sex life. This is so untrue. If anything, having to deal with a baby who's no longer getting the antibodies from your milk and has a high fever for 5 days in a row....or a baby who wakes up several times in the middle of the night and won't go back to sleep b/c the boob is gone...now that's stuff that will affect your sex life.
As for 'babying' a baby, there's plenty of people all over the world that think this is exactly what you should do!
