My baby breast-feeds and uses this bottle no problem

I bought these with my first son and when I went to purchase some more for our second child - the lids on the bottle has changed. This was a major disappointment - the older lids had a hole for he nipple so it would not leak when you went to shake the bottle to mix the formula. Fortunately I had the old lids that I can use.

I got this bottle as a gift from registering and so I decided to test it out. It works good, my baby didn't seem to get gas from it and its easy to clean.
