Hi Roshni, actually by the age of 1 - solids should be the main food for nutrition rather than milk. My 11 months old is having 3 breastfeeding sessions, breakfast, lunch and dinner and also an afternoon snack at 3pm. She sleeps from 7ish pm to 6ish am. I think your LO might be waking up for milk out of habit.
How long has this been going on for? How does she go to bed?
