Changed to Level 3 Nipples

A couple months back, we tried swapping to level 3 nipples on Josh's bottles but he choked on it so we had to swap back to level 2.

He's 9 months now and it's taking him 15 minutes to finish an 8oz bottle (if he finishes the bottle); but most of the time, he loses interest half way and doesn't want to drink any more.  So we tried using the level 3 nipples again and he loves it!  He can slug back an entire bottle in 3 minutes.  Yup, 3 minutes!  He gives out a couple of huge belches afterwards but seems content with this new arrangement.  Now we can move onto more difficult tasks...
