Time to change bottle nipple size?? FTM

Hi guys, I was just wondering when it’s time to switch the bottle nipple size? The ones Emilia has are the first ones, but every time she eats she’s been getting super fussy with her bottles. And I know she’s hungry! So I was thinking it’s probably time to try switching up to the next size? Would love some input! 🙂
