Thanks to Trish for this Frugal Baby Tip!
Today I made my own doublers from an old towel and an old recieving blanket! And I tested it afterwards compared to the Ecobaby doubler. The Ecobaby held 170 gms of water, mine held 140. I am pretty happy with that. And it was basically free! One towel and one recieving blanket makes 7 doublers!!! 11in X 5in. I made a diaper from another blanket and a left over scrap of the towel. It is so cute I hate for Andrew to get it poopy!
