We use tommee tippee and my 10 week old just went on to size 2 a couple of days ago. Things to look out for is getting frustrated when feeding. Taking a long time to finish. Not taking as much as usual. X
My LO is 9 weeks and still prefers the 0 teat. I tried the size 1 and it still feels like he is choking and taking in too much air. Is this okay
