Weaning off milk

Hi mummies My baby daughter is 1 year old. She is still very reliant on her milk powder and her feedings did not decrease (still 8 times daily) although we have reduced her milk intake from 150ml to 120ml due to her overweightness. I was wondering if babies drink milk to what age? What does totally weaning off milk means ? If baby don't need to drink milk when she grows up, what age would it roughly be? The milk powder can last until she turns 3 years old. If so, do babies stop drinking milk altogether and eat solids like us? I am a first time mom, so I don't know when it's the right age baby can wean off milk (or not?)#firstmom #advice
