Sounds like you are doing a great job and, trust me there is no WAY you can hold back a gifted kid so they will be at the same level as normal developing kids. People thinking you are hot housing your kid just goes along with the territory. Sometimes I feel like people want us to put them in a dark closet until kindergarten! wink
