Bottle help

I need advice! My baby is exclusively breastfed. He has taken a bottle a couple of times when he was about a week old. Now he’s 7 weeks old and gags on bottles. I go back to work at the new year and we’ve been trying for 2 weeks now to get him to take a bottle. Sometimes he’ll latch and get 2 sucks and then starts screaming. Sometimes he just lets it sit in his mouth, sometimes he gags cause he’s dramatic lol

I want to continue breastfeeding but I need him to take a bottle for when I’m at work

Also I’m not really looking for bottle recommendations cause we’ve tried literally almost all of them. I don’t think it’s the bottle itself but just that he’s quite literally attached to me and such a mamas boy
