Thanks for sharing this, Anna1985. It’s concerning that you found it shook your baby’s head. We have to say that none of our testers mentioned this to us – and they were all asked to test the Rockit very thoroughly. They all provided video footage of their babies using the Rockit too, and it looked super gentle (as you can see in the footage in this article)We will pass your comments on to the people behind Rockit, though. We should think they’d be very keen to get in touch with you. Can we please pass on your contact details to them?
