Sorry to hear that. I lost my Auntie in December to cancer, she had a 5 year old son too.
Keep your head up and stay strong!
"If i could fly
I promise life would be a lot better baby,
If i could blow,
Like the wind across the city i'd go
Up in the sky
That's where the pain ends for the living baby
But i cant fly, and you cant fly
So we gone have to work it out"
