7 months old prefers solids over formula.

Baby is 7 and a half months. She likes solids, eats well, but recently started refusing bottles.

I know weaning before 1 is not recommended, but assume nothing magical happens at exactly 12 months. How much milk is actually required? How dangerous it is to wean a bit earlier?

I am giving bottles all the time and don’t plant to stop, it’s just emotionally hard and a bit scary. She gains weight and is very active and alert. Pediatrician just said to keep trying but saw no issues.

Is there any research or maybe you have personal experience with it?
