As other posters have said - you are definitely doing the right thing. My health nurse says food is only fun until they are one, and that milk (BM or formula) are the most important until then.

But also just because you push solids doesnt mean he would happily drop feeds. My DS is 8.5 months old, has breakfast, lunch and dinner (1/2 cup each meal) and now has afternoon tea (toast or fruit) and still has anywhere between 5 and 8 BF's a day. But he is not overweight, doing everything he is meant to developmentally and is a happy little monkey, so it doesnt worry me

Trust your instincts - you are a great mum
