Have had a look in mothercare at the basic kind (baby bounces or you) and the seemingly flasher kind that vibrates (quite a lot - which surprised me - rather like a back massage chair!) Anyone recommend one please? We didn't have one for our first but I'm thinking this could be very useful. We had our eye on the Fisher Price Kick and Play as it has a detatchable bit for exciting baby but also a calming motion. Thanks in advance for any tips and suggestions.
