Thanks, Jaci and Caryn.
It's hard having no role models around to ask these questions but at least there are boards such as this one to find advice. I mean, there have been quite a few nursing moms at my company, but none who've worked in the same building as me for the 7 years I've been here.
The HR director is pressuring me to stop pumping, in an indirect way. I mean, when she came into my office, she said "I don't want to pressure you..." but the fact that she was asking was a sign that she was! I'm guessing that the other nursing moms at my company must have stopped pumping around 12-18 months.
This weekend my ds wnated to nurse much more often than usual--like once an hour or more! I think he's either teething or going through a growth spurt. I expected to be really engorged today but I really wasn't. I only got about .5 oz more milk than usual, too (usually I only get about 2 oz, today it was 2.5).
The important thing is that I can still continue to nurse ds even if I stop pumping. I'll see how I feel after his 2nd birthday, which is coming up in about 1 month.
