Quite some time ago I was sent a Refresh-a-Baby bottle adapter and finally got around to giving it a test run on Friday. Basically when you've got a refresh-a-baby teat in your bag, you have an instant bottle that your little one can drink from which is very handy because we all know your drink/bottle is way tastier than theirs. Unfortunately though when you share your bottle, the baby normally succeeds in swallowing about a quarter of it and spilling the other three quarters. With the Refresh-a-Baby you simple push the nipple and adapter into your bottle and voila, instant baby bottle.
The Refresh-a-Baby bottle adapters can be bought here.
