Milk bottle alternatives

Hi all. My son is starting infant care next month, and I was told to bring milk bottles for feeding. Problem is; he was never bottle fed (direct latch since day 1). [Started with cup at 6m and straw at 10m for his water intake] I do not wish to give him milk bottle at this point because I read online that this is the period to wean off milk bottle instead. May I know what other alternatives can I sub for milk bottles? Snippy cup? Straw? Thanks in advance!
