We had the Nuk Orthodontic and gumdrop type one from the hospital. She couldn't keep the gumdrop in her mouth and I didn't want the shape of the ortho one to be confusing but we had to use it in the hospital for 24 hours while she was in the Easy Bake Oven (the bili-lights) because she would throw her legs around, roll her head and disrupt her eye protection.
Once home we tried the Playtex Binky Most Like Mother - but she would spit it out the second the latex touched her tongue.
Now we have Avent Contemporary Freeflow pacifiers. The only I don't like is the handle thing one them is big - so big that Ruby winds her little fingers in it and rips out the passy, then cries until it's returned.
I like the look of the MAM ones though, might have to hit the store on the way home
