hello ImaDunce,
I followed httpman's lead to visit your site (his English is damn good eh? wish I spoke French that well) and liked it. Nice soft pastel colours; good clear message about your purpose. Uncluttered and clear. Nice work.
One thought I had is the use of personal pronoun "I".
Don't know about your part of the world but there's a lot of suspicion about charities which use a front to get money. Build a team, tell us about yourselves, get a well known person (doctor, head of hospital etc) to write a brief reference so we know you are who you claim to be.
Good luck on a wonderful project - we have a strong progam here for that purpose and it is gratifying to see. Perhaps look at some of the Aussi groups who lookk after kids in hospital. Sorry can't think of all the names but you'll find them in searches.
Final suggestion - approach McDonald's for sponsorship - they run Ronald McDonald houses here at hospitals so parents can stay cheaply on site when their kid is in a ward.it's a great service.
