I live in a big city, and am or have been taking my kids to Johns Hopkins, and I feel like I am in the dark about so much. I see some of you have written in about how and when your kids are tested, and Gareth was even talking about salivary levels-no one ever mentioned that to us. I am searching for a Doc still, and I hope that we can nip any problems inthe bud early on. Thank you for your responses-I feel stronger now and armed with more info for the next Doc I trust with my children's care. God Bless.
