Introducing Bottle

BR

My little one is just over four months now and has been EBF this whole time. Due to covid and work pressure I'm having to start to go back earlier than I would have wanted ...specifically next week. The last ten days or so we have been trying to get her to take a bottle of my milk but she is down right refusing and I'm at my wit's end. Luckily I don't have to be physically in the office full time but will be away for hours at a time/ half days and am really worried. Any tips or stories about getting your LOs to take a bottle? We have tried different types, sizes, all of it.. we have tried hungry,not hungry, lying down, sitting up ..distractions, sleepy lol aaaahhhh
