Which bottle do you use to combi feed?

My 14 week old is mainly breastfed, however we gave him at least 1-2 bottles a day of expressed milk from birth. And it all went fine Now husband went back to work, and I finally established a predictable feeding pattern, with only 4 feeds per day and 1 at night. I was too lazy to express bottle to feed myself, breastfeeding is going well and it is just so much easier for me. Long story short, now when I am going out and someone else tries to give him a bottle, he would scream his lungs out and simply go on a hunger strike. He occasionally would take a bottle from me now, but most often he would just turn his head and will try to find a nipple. In 100% of cases I give up within 5-10 minutes and he has a proper feed on the boob 😅 I am thinking of changing the bottle maybe. I used Tommee Tippee and now on Teat 2. Which bottle do you use if you combi feeding? Or perhaps some other techniques worked for you if your baby started refusing the bottle?
