Ok so he took a bottle tonight after a fair bit of protesting. DH gave it to him while I bathed DD so that I wasn't in the room. We gave him 90ml of AllerPro formula and he took about 60ml. I breastfed him afterwards. I'm so glad he took it, I hope he starts accepting it without protesting. At least if he will take a bottle I'll have options with how I move forward.
