Brodie only took a paci until 4mo (then started sucking his thumb-still does) but before then he used a silicone one.
Evan uses a silicone paci & latex nipple for bottle.
I think the main concern w/ latex is their ability to break down & have pieces chunk off easier than silicone. Someone correct me if I’m wrong. Which it seems odd that they wouldn’t have the sturdier ones (silicone) for older babies.
Anyway, I say just use what he’s familiar with. Fwiw though, I went to the Gerber Nuk website & they don’t show any pacis higher than size 2 (6mth+)… neither does Babies R Us. So maybe they don’t make them?
