Take opportunity to pump during lull moments. You’re in a meeting that has not started and it has only been an hour since your last pump. You know that in another hour, meeting will be on its peak and it will be difficult to leave. Take a quick break and pump for 8 minutes even if it’s not yet time. Every ounce counts. That way, you won’t go for 3 hrs straight without expressing. Your breasts and mind will thank you for it and you won’t be distracted during the meeting. It is like baby is snacking in between the 2-hr. interval.
