I returned to work when DD was 10 months old. I fed her on waking, on dropping her at mum's place (so 7am), she had EBM for one, occassionally two, feeds, then fed her when i returned at 5.40pm. she was drinking water and eating solids by that point.

i would express for comfort on my lunch break, or, if mum was out and about with DD, they would stop in at work for a quick cuddle and feed.

on the days i was home, she would feed every couple of hours still, but on the days i wasn't there, she didn't have any problem going without it. i only ever worked one day, had one off, worked another one, one off, so it wasn't a huge deal. it may have been different if it was full time work - but then, we don't know, cos we didn't have to do it kwim?

ETA - i think she fed more when i was home simply because i was home - who wouldn't choose perfect boob milk over water? but when i wasn't, she coped just fine
