I'm posting on behalf of a friend who doesn't use MN/other online media herself and relies on me for BF advice as I BF two children to around 2yo and became quite knowledgeable about it. She's successfully BF her first baby but they had trouble conceiving and were successful with IVF. They want to TTC again naturally from when baby is 6m (currently 4m) and are aware that while you can fall pregnant while BF it's less likely and the odds are already against them! Pref is not to give formula (no offence to those who FF we just share the view that it's not the best for our babies). Baby takes expressed milk from a bottle readily so I'm inclined to suggest she start stocking up, though I know milk adapts to baby's needs with age so wonder if this is best? Has anyone stopped BF around 6m yet managed not to FF then introduced cow's milk at 1? Any advice welcome. Thanks for reading!
