Fenella,
I am back at work full time & give EBM to Mum or Sister (whoevers day it is to have Indah)
I told them from day 1 to let her guide them as to when she is hungry, if she is grizzly & it's only been 3 hours give her the botlle of EBM, dont make her drag out til the 4 hours!!!

They understand that she is our baby & this is what we do, as it is she goes about 5 hours between bottles of EBM now & has some solids....

I give them roughly 550ml of EBM a day & I feed her as she requires whenever I am with her....

So as long as whoever is looking after her knows they feed her when hse wants it, not what suits them then I am sure you'll have no probs... Best of luck....
