Question about bf while pregnant

[stohelit]

I have read that supply usually diminishes (or disappears) at 20 weeks. My question is: does this happen gradually or is it sudden? I think my toddler would not cope well at all if it were to happen suddenly.

Any advice on bf while pregnant or tandem feeding will be appreciated too.

In my experience, my supply got lower over time but never disappeared.  My DD was able to adjust throughout and is still nursing (approx 3 times a day) and I'm 33 weeks pregnant.  At this point, DD is looking forward to sharing nursing with the baby.  I did take advice that I read on a thread here and have told her frequently that when the baby comes there will be tons of milk for her.  She's old enough that I think this helped her cope with lower supply periods. 

Good luck.
