I came across a new invention today - the Flipple - http://theflipplecompany.com/ 
The idea of the gadget is that if you are out and lose or forget your baby bottle you can turn any water bottle into a formula bottle.
Great idea - I could have used one of these when my ex-daughter-in-law dropped off my grandson with no bottle - and I had to go round the neighbourhood to ask to borrow a bottle!
But in the video, the designer suggests that you can stop even bringing baby bottles when you go out, just bring water bottles.
Is this a good idea? Seems like the idea of using disposable bottles to feed your baby will create a lot more garbage to deal with.
And as much as we don't like to think of it, won't this just make it easier for parents to feed their babies something other than formula? Sad to say, some parents do feed their babies soda, "juice" drinks, etc. instead of formula.
Sure, if they are going to do it anyhow, not having one of these gadgets won't stop them - they can just pour it into a baby bottle. But perhaps the idea that you can screw this onto any bottle, will give some parents the wrong idea?
Or maybe I worry too much?? LOL
