My other son was nursed until 4 months than formula due to pregnancy early but anyways when I switched him to milk the easiest is to nurse less and pump into the bottle a little and add milk and each time slowly add more milk than breast milk and eventually it will work. Some kids dont like a bottle of milk. Maybe try a cup with a straw or a sippy cup
That's how we got my second and first to drink milk. Both my kids are lactose though.

My oldest was nursed until he was 2 years and 2 months. B U T he was also fed normal food and drank juice. I only nursed him for naps and bed time. Other than that he had normal stuff. It's hard, they cry and fight but I also found out my son was lactose intolerant and that's why he didnt take to milk. When we did get him to take milk he was on the 2% lactose intolerant milk and he LOVES IT. hes 4 now.

I'm in the middle of weaning too. I've been dwindling down kind of slow. Remove and replace one breast feed session throughout the day each week. Leave morning and night feed for last. My baby won't drink milk so I'm having to give him juice or water to fill that in, and other dairy things to replace milk like cheese and yogurt. I've been trying oat milk and horizon organic milk because it's sweeter than other milks and he does good with that. I don't force it, if he sips great if not then I'll give water or juice. Just make sure to put left over milk back in the fridge right away to avoid spoilage. Also, I've been doing a little bit of milk in breast milk to help the transition.
