Level 2

Nathan has graduated to Level 2 bottle nipples.  The Level 1 nipples were "slow flow" which mimics a natural nipple and strengthens the baby's mouth muscles.  Now that he's older, Level 2 are "medium flow" which lets him get the milk faster.  He's eating so much more now (140 ml, 6 times a day), it lets feeding time go by much faster, and his mouth is already well enough developed.  He's a big kid now.
