How devastating for you all - first you and now your baby, life can be so very cruel sometimes - my heart goes out to you all!!!
Chemo & Radiation are bad enough for an adult, let alone a small child, I will pray and keep you all in my thoughts that all goes well from now on & that the MRI scan shows that the operation was a success so that these other treatments won't be necessary or at least not as harsh.
Poor little guy, how do you even begin to help them understand all that is happening to them. Stay strong in yourself for yourself & your son & know that there are people here to offer you support, a shoulder to cry on, or even just a friendly ear to listen while you vent your anger & frustration in a safe environment.
Love & Hugs to you both, stay in touch.......
