Re: URGENT: No letdown?!
This is a tough situation!
I exclusively pumped with ds1 also, for 13 months, and there were a couple times (usually for a couple days in a row--and I was pumping up to 6 times a day), where this would happen. I know it's not great advice, but for me it was always stress related. Has anything changed? Are you any more stressed/under pressure than normal? Relaxing, and "talking" yourself into having a letdown might really help. Also holding your baby, or thinking about the baby could help.
This doesn't have to be the end! It'll happen, just keep pumping away (also, give yourself more time to pump--if it usually takes you 10 minutes, pump for 20).
