Kitty- Wyatt prefers advent but I think it's because it was his first.
We have tried nuk which I hate, the teat is weird and the actual dummy is quite unattractive.
We have tommy teepee which he isn't a fan of, the base around the mouth is quite heavy compared to the size of the teat so it takes a hard suction to keep it in. So it depends on his mood if he will take it.

I'm planning on trying an old fashioned happy baby dummy. It has quite a large teat which I think will be better for Wyatt as he is dropping off to sleep. That's when his dummy falls out alot requiring me to walk in to pop it back in several times.
Plus the HB ones are $2 rather than $8-12
