Please help 😩

So my baby has been EBF for 7 months. I need to have a procedure done with dye that can get into my breastmilk, so I can’t breastfeed for a whole week. My boy will not take a bottle at all. Or a sippy cup. I’ve tried EVERYTHING. so many different bottles, so many different sippy cups, dad trying to feed him, dad taking him to the park to try to feed him, everything. I feel at such a loss. I don’t know what to do. He is so stubborn and will not eat. What do I do?!
