Perfect to stick in the bottom of the diaper bag until you need it

GreatDad
has always recommended the nipple adapter, which was previously
available only on eBay from a discontinued line called LionHeart. Now
BabySport has resurrected the idea. The idea is simple: using a
converter ring, you can make just about any common water bottle into a
baby bottle. Just add formula and go. Perfect to put in a sealed bag at
the bottom of a diaper bag, in the glove compartment, or in your
stroller. Eventually, you’ll find yourself in a situation where you
forgot the bottle or dropped it in puddle and urgently need a backup.
TheBabySport Water Bottle Nipple Adapter
is even cheaper than the old model, at $6.99 for a 3-pack. And, it was
re-invented by a dad. Your wife will laugh when you show it to her, but
it will save you one day.
