Still, if you are nursing and find it’s time to switch a baby to a bottle, it may not always be an easy transition. Thankfully, baby bottles have come a long way from the basic offerings of yesteryear. You want bottles that not only mimic the same flow, flexibility, and comfort that mom can provide, but are easy to clean and don’t require a PhD to assemble them.
