To create more space around the hips, the lateral hip straps can be adjusted. If the fit of the harness is becoming too tight overall, we suggest removing the inlay cushion, which is meant to regulate the depth of the seat as children grow. Also, there are three pairs of slits in the back of the seat which correspond to the different stages of growth of the child. Please refer to your user guide for details on the appropriate settings. Please note that it is not safe to strap in a child only around the waist.
