I have been feeding her 4 times (once on waking, once mid-morning, once mid-afternoon, once before bed) but she's really uninterested in solids and it;s a struggle to feed her 'proper' food at mealtimes and a friend suggested that maybe she's getting too many calories from breast milk so can't be bothered with eating. Should I be dropping a feed? How much breast milk do they need at this age?
