K.W.
I used these with 3 of my kids and they were life savers when we were in the car or shopping. My boys would always scream to eat at the worst possible times so these would allow me to continue driving, shopping,etc and they would be happy. It is easier when they are a little older but I think I used them at 3 months old. I did hold my babies when we were at home or somewhere where I could sit down with them because I enjoyed the feeding experience but sometimes you just can't and the Podee bottles are lifesavers!
