If you are using Playtex VentAire Advanced wide 6oz bottles STOP.
The measurements on the bottle are incorrect. I have been dealing with Playtex since early April. I sent them my set of bottles per their request. They tested them and say that they are confident in their calibrations. I requested documentation of their testing and/or video proof and they told me no. So I did my own video to show the results.

This is very important and they are doing nothing!! Improperly mixing baby formula can lead to kidney damage and even death. If you are using these bottles, test them for yourself. If you are getting the same results PLEASE contact Playtex at (888) 310-4290 and stop using them right away!
