The shape of the pacifier helps it stay in the baby's mouth without popping out. The latex version is shown here, but I actually prefer the silicone version as it is odorless, tasteless, and hypo-allergenic. This chair has been indispensable for us due to our colicky baby. It takes one D battery and will vibrate like a moving automobile. Our baby slept through the night for the first time in this thing.
Minimal assembly is required.
Although this toy frigtened our baby the first time she heard the sounds, now she really loves it. It keeps her busy, and you can take off the hanging toys and put your own up if baby gets bored. I like this cradle because it is classy-looking, made of hard wood, and rolls easily from room to room. On the downside, assembly is required. Those days are gone.
