DS is breast fed morning and evening, and has two bottles during the day of expressed milk (I'm back at work). He will happily drink water from an open baby cup, they look a bit like shot glasses, but if you give it to him to hold he throws it. He has a couple of 360 type cups one is Tommy tippee and the most used is a Nuby one, again he's happy to drink water from them although he does mess around with them a bit. He's ten months now and whilst it doesn't seem long ago I was getting him to take a bottle instead of breast so I could plan to get back to work, my HV tells me he should be stopping bottles now. The 360 cups he doesn't drink enough from in one go for me to use them for milk and I'm worried about the parts getting a bit manky with milk despite cleaning. At nursery they seem to have handled free flow soft spout cups which they say he's great with, but I've read conflicting information about spouts and teeth Vs open cups, and then also that any valve even the soft 360 type aren't good either. Any advice for a befuddled first time parent who's maybe done a little too much research?!
