when do you go up a size in pacifiers?

Question

My daughter uses MAM pacifiers she's still using the newborn ones, she's 3 1/2 months when should I switch her to 0-6?

Answer

As long as she's using them don't bother switching...

Answer

You should already be in the 0-6

Answer

It says newborn to 2 months so I would go up

Answer

If it looks to small or like she could swallow it I would go up

Answer

Those are the ones my son uses. I have some newborn ones and 0-6 month ones. What ever one we find first is the one he gets.
