Hi Hawksey
I was in a similar situation to you when I returned to work, my DS was a little younger though.
He is now 14 months old and we still bf exactly the same as you on the days i don't work, and on the days i do work, he is happy to go to sleep with cuddles from nan (mum looks after him whilst i'm at work). I was so stressed before returning to work as the only way he would sleep was to feed to sleep, he also never took to ebm or formula (he was 6 months when i went back), but when it came time he simply learned to survive without mummy for a few hours. I never thought it would happen but they do sort themselves out!
None of this has probably been much help to you but I just wanted to let you know that you can work and still bf!
