Hi Oops,
I went back to work like you and had a similar problem . If you really want to drop to morning and evening feeds only i think you have to do this every day and just get through the next few days.It shouldn`t take more than a week to settle down. I expressed at work by choice because i was too uncomfortable ! An NCT bfing councellor told me something once that really helped get me through.She said i could feed on Mondays Wednesdays and Fridays only if i wanted to !!!! Basically i fed dd1 whenever he wanted it on my days off and morning evening and night work days.It worked for me .Can you express maybe just once during the day ?
