Hello. I have 2 girls (3 yo and 14 m) and every time we put the 14 month old in her car seat, she slouches down, pushes stomach out, arches her back and sometimes holds her breath. This is actually better than before where she would cry the entire car ride. We upgraded her from a rear facing carrier to a front facing car seat and it did not help. Soon we’ll be making an 8 hour drive for the holidays and aim to drive at night so she’ll sleep through the drive but to prepare for the worst... any advice people?!
