I am one of the those mums who never got her baby to go onto a bottle. Tried from birth to 4 months with dd screaming bl..dy murder all afternoon, then falling asleep, then waking up hungry and still refusing bottle. If she drank, it was over 3 hours and I never got her to take more than 2 oz at a time.
It sounds harsh - but dd was very small and not growing according to the growth charts (but that is another story). The HV, hospital (dd has some early health issues), lactation consultant, speech & language therapist all recommended bottles. Me/nurses/HV etc (and their mother) tried diff bottles (not Habermann - tho' if I can bring myself to have another baby, I will try it), diff teats, different persons giving the bottle, different ways of holding, me in the room, me away, formula, expressed milk, milk warm/cold/room temperature, semi-starving, feeding when full ...
I gave up - dismissed everyone and decided to exclusively bf her. Was never happier or calmer in my household.
In the end, extended my maternity leave to one year and by then, dd was happily on a cup with cow's milk. Now dd is 2 and loves the bottle - to play being a baby with! Sheesh
