"Food is fun until they're one" - so yes, breastmilk, or ABM is the primary food source for the first 12 months.

If you've made it to 6 months successfully breastfeeding, unless you have some medical issue, there is no reason to expect that your body won't be able to continue to provide your baby's breastmilk needs. They can also drop feeds because they're getting too much in the way of solids first, so they're already full, and don't want as much BM. So milk first, then solids is the way to go.
