Hi Nanuaru,
Please don't feel guilty,whatever has to happen ,it happens,sometimes life just don't work our way,but to tell you the truth i feel myself blessed that my daughter is born in an age where oral iron chelators and other medicines are available,other wise 22 years back i saw my cousin dieing with the disease beacuse there were no chelators available at that time, at least in my contry. So cheer up ,roll up your sleeves and be ready to fight,
we are all here to support you,your daughter is lucky she has a doctor for a father,you'll be able to understand medical terms more easily which i don't
don't worry your cutie pie will live a long and healthy life INSHALLAH.
ZAINI.
