So I currently have 2 rock-n-plays. One i got as a registry gift, it's the snuga-puppy and it DOES vibrate and cost $75. The other was on sale at target for $50 and is the monkey and DOES NOT vibrate.
I personally think the monkey is cuter... specifically the background fabric (cute geometric stuff on monkey vs. pinkish dots on puppy). If i were going by looks alone, i'd keep the monkey and return the puppy for the extra $25 back.
BUT, the puppy one has vibrate.... do i need that?? have you used the vibrate feature a lot in the rock-n-play?
