8 months - replacing night BF with formula

[hammeringinmyhead]

I've breastfed DS for just under 8 months. He has taken well to food and has definitely dropped his milk feeds during the day. He has a last feed of a bottle of formula at 7.30pm. However he still, without fail, wakes at about 2am and 5am clamouring to be fed when I don't think he needs it - I think he just wakes up and gets bored! Cuddling and shushing etc don't work, and he only feeds for about 10 minutes.
Has anyone had any luck replacing a breastfeed with a bottle bang in the middle of the night and it either a) being less appealing so stops unnecessary waking or b) filling them up a little bit so waking is more like 6-7?

I would not replace BF with formula! Babies that age will wake for bf regardless of them being hungry or not. Some just need to be close to you, and the breast is his way for that. If you really want to stop the breastfeeding, I'd probably give him water rather than the formula. They don't need to eat at night at that age. The BF is made for the baby and he can have as much as he wants of that. Formula is like a full meal, and can also damage his teeth. I read some Australian research that said breastmilk won't damage the teeth, despite what all dentists say. My DD was breastfed for 3.5 years. I stopped the nightly feeds when she was 2.5 and her dentist has always said her teeth are perfect.

I agree with Sofin, would it not just be easier to bf him than get up and faff on making formula by which time he will be agitated and more awake and therefore harder to get back down?
