Back to work

I'm having a very hard time going back to work. I had my 6 week check-up last Thursday, and since then have planned to go into work just about every day, but somehow it seems I spend the morning sleeping or feeding Sylvia, then the afternoon making sure she's not too fussy, and I'm never sure I've pumped enough milk for her to make it through the few hours I'll spend at work, and suddenly it's evening and I've spent the whole day at home getting nothing done. It's amazing. Sylvia is a whole new way for me to procrastinate. I'm sure it'll be better when she has more of a schedule, right?
