How do you WOHM with lots of meetings schedule pumping sessions? I'm going back to work July 1st; my BF LO will be 4 months old. I see I'm already getting meeting requests for my return.

I typically have 6 or so meetings during the day, usually 3 or 4 back to back. I'm thinking about blocking out time on my outlook calendar now so meetings will have to be scheduled around it. But I'm concerned my boss is going to be annoyed by it and prefer I fit in pumping around meetings.

How do you schedule? If I should block my calendar in advance, how much time should I block per session?
