Exclusively BF DS (6 months) won't take a bottle or a cup where you have to suck like a bottle. But we are having some success with a free-flowing cup (because I have removed the non-spill valve), as long as I gently feed him the milk/water bit by bit - trouble is that when he tries to do it himself it rather predictably goes everywhere! Can anyone recommend a cup or beaker where you can adjust the flow? Preferably with handle/s?
