I've heard of parents putting fizzy pop in the baby bottles with the teets. FFS if your bab is that young it does not need to be introduced to fucking beetus drinks. When I was a kid I got fizzy pop a few times a year at birthday parties. Apart from that it was water, milk or diluted fruit juice/cordial. I'm only 34 but it seems that in the last few years we have gone from a society that treats kids to unhealthy food occasionally to one where it's the norm.
