Girls, hello. Can you tell me who's kids had blood drawn from their veins? We're only two months old. There's still some jaundice left, so yesterday they told us to have our blood work done for OАК and biochemistry. I'm worried where we can find a vein on the baby and even get blood if they're constantly moving, waving their hands and feet...
