Sleeping at the Dinner Table

Alex fell asleep again at the dinner table at 6pm tonight. My "worry" radar is up, and I'm concerned that he is either getting sick, or his counts are dropping again...

I hope it is just the innocent exhaustion of a 5 year old boy who played with his buddies today, and just wore himself out.

I wonder.

Will I ever get to shake the worry of the chemo and cancer side effects? Even once the cancer is just a ghostly nightmare, separated from my son by time, and healing?
