I'm not a mother of two yet but I can imagine that there would be times when this could be a great option, like when you have a screaming toddler and a hungry baby. I can't imagine the parent of a healthy baby using this bottle all of the time. It's normal to want to enjoy those feeding cuddles.
I'm sure they'd be designed in a manner that prevents choking Atropos, especially if they're already being used with babies with feeding issues.
