When to stop giving breast milk/formula?

Am
I breastfeed, my baby has never had any kind of formula. But we started solids, which the pediatrician recommend. Since I've started giving baby foods, she still nurses but seems more interested in real food, rather than just milk. She'll be 6 months old soon & I've googled things & asked people & it's really controversial. Some say you can just give baby food alone at 6 months if that's what we decide. Some say still give milk or formula for a year. Some say switch her to baby foods plus vitamins & add in 1% or skim milk until she's a year old. I don't want to wean her off because I feel like shes getting all the nutrition she needs. But with her teeth coming in, shes constant chewing on me & biting & honestly seems to prefer baby foods over the breast, atleast once or twice a day.
