Query: LEAKS

I would not recommend these bottle to anyone. They leak on us all the time. No matter how tight you put the cap on, no matter how many times you adjust it and no matter how many times you pop in and out the nipple they leak! Granted they do not leak every time, they only leak at the most inconvenient times. When they leak it doesn't drip out it pours.
