At 6 months Jake went down to 4 milk feeds (from 5 or 6) and up to 3 solids meals (from 2) and down to 2 naps (from 3). So it was roughly like this:
6.30/7am BF
8am breakie
9-10.30am nap
11am BF
12ish lunch
1-3pm nap
3/3.30pm BF
5pm dinner
6.45pm bottle.
Morgan is a bit more random and not quite 6 months, but she has 2 solids (lunch and dinner, will add breakie soon though) and 5-6 milk feeds (the last one is a bottle, the rest BF), and is still having 3 naps but is a bit of a cat-napper so may not go down to two for a while.
What you're doing sounds ideal, but I'd increase to 3 solids soon after the second meal is established.
