I have found tommee tippee better If you are planning on using breast and bottle.
I have bought three of thm for newborn... Usually my family uses tommee ones...
My sister inlaw uses them for my niece she has a lot of gas that makes her fussy,& the bottles make the situation much better! they are great!
This will b 2nd time i will b usin them n av used tommee tippee both r gd my sister uses avent aswell
I have heard they are good,I'm goin with tommee tippee though !!
They are good bottles and easy to take apart.
Also, over here those new Tommee Tippee Closer to Nature ones look good too.
they are quite popular here in Australia, i think the teats on them are quite good too.
