I have three sons like you, and three sons who had to be taught to read with phonics at age 5-6. The instant-readers don't miss out on learning to read in public school, but they miss out on everything they could have learned with their ability, because they're held back to the level of the "other" kids in their grade, who didn't learn to read because they weren't taught.
So far, three daughters have had to be taught to read. The 4th isn't 2 yet, so I don't know how she'll turn out.
Unless I’ve lost my ability to add, you’ve got 10 kids!
Congratulations!
