My DS is, it seems, like A LOT of other breastfed babies and is point blank refusing the bottle. Tried all the tips on here - but haven't the heart to starve him onto it yet. I go back to work in about 5 weeks and need to get something sorted ASAP. Has anybody put a breastfed baby straight onto sippy cup and skipped the bottle thing altogether? Is this possible when they're about 4-5 months old? If so, any advice on how to go about it and what cups are best to use would be GREATLY appreciated. I am hanging on to hope that this will be possible and DS will love sippy cup and only have disdain for bottles.......
