My 9 yr old son had a medulloblastoma removed in January. He then had six weeks and one day of radiotherapy which finished on 20th March. He goes to bed around 10pm but is really struggling to get up in the mornings. Today I dragged him out of bed at 11.15 And he can get up later if I leave him. He has recently lost a little weight due to lack of appetite and maybe from missing breakfast. Family members keep telling me that he shouldn't be this tired and sicky now and that I should be firmer with him making him go to bed and get up earlier so he's not skipping breakfast.

So, is it normal for him to be this tired and sicky feeling now? I feel like I'm doing my best but it's not good enough.
