Im going back to work next month, have been exclusively bf Ds who is now 22wks we've started giving him little bits of solids which he loves, anyway as im going back to work i have been thinking about starting him on formula for daytime feeds only.. will it work? Im dreaming thinking that id like to still breastfeed in the mornings and evenings but will it work or will my milk dry up? 
sorry ftm and ive never been able to get much expressing so im worrying that he wont have enough milk while I'm at work.. any advice would be great
