So after lugging my pump back and forth to work everyday for the past 9 months, I am going to starting leaving it at the office. I'll still take the bottles and flanges home to wash each night but the pump itself is staying put. I rarely pump at home and if I would need to, I have the pump I used with DD. I'm just tired of lugging all of these bags each day. DS turns 1 in a month and I only plan to pump until then but am I crazy?
