With my DD I purely bottle fed medicated formula but now I'm having DS I wondered if there's any benefits to bottle feeding him expressed milk as well as formula?
Is this combination frowned upon? Would I be making things more difficult for myself in terms of his feeding? I wouldn't be comfortable doing 100% expressed feeds but there's a risk he'll turn down formula after having it surely? Or are they not so fussy? 
I've never used a breast pump in my life but I do produce a vast amount of breast milk even for over a year after my DD (that's without feeding). If my DS could benefit from this (but with actual breastfeeding not being an option) I'd like to get some use of it. Due next month and already been producing 'proper milk' for a while x
