I have a few variflow tommee tippee teats. They were bought new and my little boy tried using a couple of times but could not get on with them, kept causing him really bad air in his tummy lol, tried always drinking to much. Ill get them out if your interested? And do you need any 3-6 months vests at all? I have a whole bundle and there very sweet, they have jungle animlas on them. Let me know x
