My baby was 13 months old when I bought this seat; by receiving it I realized that it was a seat from 18 months; therefore our baby tends to slide to the front seat and we must stalling with cushions and belting with a scarf for there to be installed .... pity that the descriptive not be clearer . But as this seat will match perfectly to my expectations a few months, I did not wish to return, though, until our baby grows, it forces us to tinker a bit ...
