Toddler milk in bottles??What is your toddlers eating routine?

My almost 2 yr old drinks 3 8 oz bottles of milk a day. Mainly to soothe for nap time/bedtime and when he wakes up in the mornings. My dr already told me to cut off one bottle he doesnt need that much milk and he’s a bit overweight(he loves food) . So he wakes up 6:30-7 am and drinks an 8 oz bottle of milk. And then breakfast around 8:30-9 and then lunch at 12. Then nap time with another 8 oz bottle and he sleeps until 4 pm ish. Then at night for bedtime he drinks another 8 oz bottle at around 8:30 pm. I know I need to change his schedule…. Or bottle habits. I know I need to drop the bottle all together. We have a 6 month old also so I know I need to get it together because I know not all toddlers wake up to drink a bottle of milk? Should I start by cutting off that bottle of milk when he wakes up? Do I give him breakfast right away when he wakes up? What is your routine for your toddler? He will be 2 yrs old on June 4th.
