Query: These bottles leak too much

I found these bottles to be very frustrating. If the cap wasn't put on just right the bottle would leak horribly.<br />Even if I did get the cap on without leakage, all my 5 month old had to do was bump the cap causing it to move a fraction of an inch and formula would be dribbling all over him. Then I would have to stop feeding, take off the cap, put on the nipple cover and put back on the bottle in order to get it closed just right again. The only reason I tried them was because I needed a wide mouth bottle with a medium flow nipple. These are definately not worth the money. If I could, I would rate them a negative 10. I find Playtex Disposable bottles to be the best......if only they had a medium flow nipple.
