To dream feed or not?

[Ehc1989]

Hi all, my DS is 15 weeks old and is breast fed but has a formula bottle at around 7:45, and a quick boob feed then is asleep by 8:30pm. His next feed is between 3:30-4:30am but after that it’s frequent wake ups (not to feed till 6:30 onwards). I’m wondering whether a dream feed around 10pm would help him get closer to a 6am onwards wake up. Any advice?
Also - I am aware one feed a night is great for his age but just wanting to hear others experiences on the dream feed 😊
