I am very happy to report that Avery is doing very well

and I know that the prayers and postive thoughts and support of all my extended family, in RL and here on the DIS and the internet, have had an impact.
He had a spinal tap yesterday to check the spoinal fluid for concentration of the leukemia cells. At the same time they gave him his first dose of chemo, a direct hit to the spinal fluid. Then last night he had more IV chemo.
Today he had oral chemo, and IV meds including steroids to control side effects. And meds to help his kidney function...the chemo will kill the leukemia cells and he will expel them through his urine. Of course THAT causes side effects too...like increased appetite. His oncologist said that for today his job is to "play, eat, drink, and pee". He did real well at all of those endeavors today.
Apparently some of the adolescent patients have taken a liking to him and have shown him how to "ride" his IV tower as he makes his way around the floor. Today his mom was pushing him around and toppled the IV pole, 2 IV bags, him, and the 7 stuffed animals along for the ride attached to the various clamps and hooks. DIL said about 50 people came running. He got a little air in his lines but everyone was unscathed except for DIL who said it was probably the first of many embarrassing "medical mom" moments...
so she too is drawing strength and maintaining her sense of humor
The docs are VERY pleased with his progress thus far I thank you again so much!!
