I am sorry to hear you are going through this. The first thing I will tell you is that it WILL be okay! My daughter was also diagnosed with lead exposure at the age of two. We bought an old farm house, and unbenounced to us, the owners son had recently painted all the interior windowsills with lead paint. I completely understand how you feel. Sammy's levels were at 11, and I completely freaked out, wanted to sue the previous owners (we had the house only 1 year). The thing you need to remember is that levels of 10 or more are reportable, meaning the dr. is legally responsible for reporting the levels to your local health department. Keep in mind that this also means that your child is on the very most LOW end of the spectrum! And, levels where children display actual symptoms of lead exposure are MUCH higher (around 40 or so), of course this does not mean that you don't need to act immediately, I am just trying to reassure you that your son is going to be okay! Here is what will happen; the health department will contact you, or you can even call them - they are there to help you! They know this is something that has happened to you - not something you did. They will give you advice on how to proceed, if I remember correctly, they sent us to the hardware store, like ACE hardware, who carries lead detection kits. Since we were ready to completely tear the house apart, it was indispensable in finding exactly where the lead was coming from, which was the old paint - my husband even found the old paint can the previous owners used on a shelf in the garage. We had grandma & grandpa help take my daughter for the weekend, and went to town on the windowsills - first sanding all the old paint off, then priming the "heck" out of them and painting with super resistant paint . . . this was the quick fix that the health department recommended, the next year, we tore everything out, replaced all the windows (& sills) and remodeled our whole first floor - which we had planned to do when we first bought the house. You should test every painted area in your house, as well as your water (from all sinks), and someone had previously posted, if you live in an older home, there may be lead water pipes, which you can also fix by going to the store and buying a water purifier that attaches directly to your faucet. Another not well known fact is that some plastic miniblinds are also made with some lead content, which can produce a lead "dust" that can be incindentally ingested by young children, you can also test these with the detection kit, and take them down & throw them out if needed. Your Dr. will want to test your son regularly for about a year, to make sure his levels go down & stay down. Sammy's levels dropped to 5 after only one month post our abatement. As I stated before, your local health department will (SHOULD) have you all the information you need. But please remember - this is NOT your fault, lead is a silent, undetectable poison by they naked eye. Which is exactly why drs and hospitals test for it.
