Got a major question. Yesterday was the 1st time that dd was in her booster (Vivo) on a longer trip since the time she went to an ice show in March I think it was (she did not do well at that time). Yesterday on the way there she fell asleep no head slump stayed perfect so much better then harness in the GN. On the way back she was awake and every time I looked back she had the belt right etc but I know she moved around. She did put her feet on the back on my seat but her legs are so long I know her rear was still back against her seat and the lap shoulder belt was still in the correct spot (everytime I felt her feet I looked back). She did move her head a little forward but not totally out of the wings. Is movement ok as long as the belt is where it should be and for a 5 yr 45lb and 40 something inches tall more time in a booster is ok now right?
