How do I use my 3-in-1 glass bottle?
It’s pretty much the same as our other Tommee Tippee bottles. You just need to take a little extra care when putting the teat and bottle ring together.
The best way to do this is to carefully pull the teat through the ring in different directions to ensure the silicone lip fully ‘clips’ over the edge of the bottle ring. The area where the teat and bottle ring meet should be flush.
