Up till a couple of weeks ago, Adam was using the Tommee Tippee Closer To Nature slow-flow teats. I never thought he fed slowly, he'd take maybe 20 mins to finish a bottle, but he started fussing quite a lot and pulling on and off. So I bought a pack of two variflow teats and he seemed to get on ok with them, didn't seem to feed especially faster, more dribbling and spilling of milk than before, but nothing too excessive. We were still using a couple of slow-flow teats but when he got them he was getting a lot more frustrated, like he realised that sometimes the milk came out fast and sometimes slow. So I switched totally to the new ones. Now he's suddenly getting through his bottles a lot quicker, it's like he's barely started it and it's gone - 7oz in 10 minutes flat without a pause. Is that fast? It seems fast to me! If we try to wind him part way through he screams blue murder. He is spilling a lot more than before and today he's had really bad wind. I was wondering if the teats were too fast? I know he can control the flow but since he's been used to working for his milk and that's how fast and hard his little jaws and tongue move, maybe he's getting it out too quickly? He's only choked a couple of times but he clearly has too much milk in his mouth if he's dribbling it. He's always brought up a certain amount after a feed, that hasn't improved or got worse. Should I change to size 2s? I don't want to go back to size 1 because he was clearly quite peeved with them!
