no wobbles - no idea why they discontinued them - i did phone tommee tippee and they just said they had develoed a new teat in orthod. silicone - but ds wont take it - i then asked if they could give me the model no. of the teat and the manufactuer so i could contact them myself in case they made the same teat for a diiferent brand but the so helpful tommee tippee care team said that this was not possibleThanks for all your help i had thought that someone else would have had this problem and had alreasy souced a viable alternative but it would seem that big O is really the fussiest babe in ireland - quite possible the world
