When SAP was born we got a super comfy boppy bouncer that vibrated and soothed her in comfort. But she didn't like it! she liked it when she got older but it really wasn't much use except a nice place to lay her when we were making dinner or something. I much prefer something that seems more natural to baby, like the Mama Roo! It has 5 unique motions that are similar to how mom would sooth baby, not vibration, that's not natural!
