This product is for LAZY parents! Feeding your child is a great time to bond! Why let a  bottle which can cause MAJOR gas becasue it dosen't have a valve to hold the milk in to the straw! That makes for a VERY fussy baby which leades to mom or dad or both being very frusturated! The other thing we delt with was clogging of the straw! This bottle was a waste of money and waste of time! The Podee Hands-Free Baby Bottle was one of the worst purchaces I have ever made! I would NEVER tell any one to buy it! After using the bottle 2 times the first time our daughter got very bad gas and cried for hours...
