I have the Tommy tippee one x
So do I, when I have put formula in it I just take out the middle shelf in the steriliser and it fits in no problem x
Oh lush! Do you also put the lid in the steriliser also? X
If you take the shelves out it will fit :)
Which UV steriliser do you have? If you do the hot shot method you don't need to sterlise it as formula isn't going in it x
