Breast feeding & bottle feeding?

Nessie • 💐

So my fiancé told me a few days ago that he would like to experience what it’s like feeding our son when he’s born (Currently 35 weeks). I thought it was really sweet of him to wanna be involved & I’d love for him to bond with our child too! My question is, can I breastfeed & pump? Id be putting the breast milk in a regular bottle for my son so my fiancé can feed him too. How exactly do I need to go about doing this? What’s your experience on doing it with your child? Did they adjust to both or would they only take one or the other? I’m worried my son will choose between the two & one of us won’t be able to bond with him how we’d like to!
