I was in hospital with neutropenia (following chemo) while my first grandchild was being born in the very same hospital. When I got out I made a beeline to see him and 6 1/2 years on I still love him to bits. His other gran died of cancer the year he was born - she never met him - so I feel incredibly lucky to be here and able to help with his care. He is in school now so it is not as frequent as it was, but he has since then become a big brother, so I have the joy of looking after the cleverest two-year old girl in the world! (No bias there, of course...). To answer the question, yes, it is exhausting, especially as my body has never really recovered from the cancer treatment, but I just have to set limits to how much I can help. I am 66, by the way. I had to reduce the time I looked after the wee girl a year ago, after she began to walk, as I felt I was so tired that I was not going to be able to keep her safe. And now she runs faster than me! Thank goodness for prams, where we can keep them "contained", at least for a while.
