i went back to work when DS was 7 months, it was the right thing for us.
I was still bfeeding for the 1st 4 months ie until he was 11 months (he is 12 monthsnow) and i just expressed or went and fed him (5 mins from me). by 6 months he shouldbe ok to have 1 or 2 bfeeds while you are gone...I did have some formula for him but that was bc i travel for work so i had days when i was not there to feed him (not onight until he was 10.5 months). My DH took the opp to drop to 4 days per week, bc we could afford it (i am the primary earner) - we eah work 4 days per week now... original plan was for us each to have ds for a day a week so he had 3 days at fdc (no family here) but we have opted for a 3 day family weekend as our life is pretty hectic and we need the time the 3 of us. this has been v hard to manage but good for us all - i think you will know what is best for your family. if he is with gran and dad it is a lot easier than cc i would think... and just to let you know you can work and bfeed - it just takes some organisation! working from home sounds fab - i do that often - make sure someone is there looking after ds but it means you are still around. sounds like you have a flexible work if you want it... best of luck
