I can see why they have adult size pacifiers. I ordered some ones for 18-36 month olds and they are so small. I can almost fit the whole thing in my mouth. I for sure would not sleep with a baby one. Although it’s good for during the day. I also got 3 new sippy cup like bottles. One has Mickey Mouse on it, one has Cookie Monster, and the other is blue with musical instruments. I haven’t tried them out yet but I’m about to.
