I have to say these are the best ever bottles to be on sale.  For the first 6 weeks of my little lads life i used to spend about an hour trying to break his wind. Then i found BFree bottles, yes they are expensive but they are worth every penny.  After my purchase i did not need to break his wind, due to the magnificent sytem in the BFree bottles, the person who invented them is one cool dude.

They are also known as "Dr Brown"

£10.50 for pack of 2 bottles from Boots.
