Ive never been asked, infact I remember the second time straight after he'd been given his jabs, I said to the nurse thank god ive got a bottle to give him as its stops him crying and she said in a really catty tone, most mothers like to breastfeed not give a bottle.
So I said well I don't fancy breastfeeding in the waiting room with a load of sick people which is why ive EXPRESSED some milk.
She didn't know how I was feeding him until I said at the end about the bottle so if id not mentioned it she'd never of known. Felt like smacking her in the mouth !
The other times Ive always brought up bf first.
