My LO is 10 weeks. Yesterday, I purchased two medium flow nipples yesterday and tried them on my LO as I've been having alot of trouble with him only taking 1-2 ounces at a time lately even though he can (and used to and occassionally still does) eat more akin to 4 ounces at a time. In fact, it has gotten to the point that it is not only a pain in the behind (because he eats more often), but I've also noticed him not gaining as much weight. Plus, he take forever to finnish a bottle when he does finnish it. On the first try, he ate 5 ounces and on the next try (just a couple of hours later) with the faster flow nipple he ate about 3.5!
So...my question is this - Is there any reason not to switch him to the faster flow nipple? Is there any danger in switching too soon? It does say 3 months on the nipple. It seemed like the feeding was a little messier (had a few more dribbles out the mouth), but he didn't choke on the milk or anything.
