My Embrace is moving more than an inch from side to side and I have tried reinstalling it. THe latch is tight!!! the level is correct ... I have installed it in the center. I Don't know what is wrong! When my son was first born I had the seat installed at the fire station! they installed it outboard... my Ped. told me that it is safer for the seat to be in the center for side impact. What should my next move be?
