DD is 14.5 months. She's been slow-ish with her gross motor skills, everything else fine. She's not cruising, walking with her v-tech thing etc, but I've noticed that when she stands up she always goes on her right leg first then left leg, iyswim, and when she needs to sit down, it's always her left leg that goes first. Does this sound normal?? They are they same size, if that helps.
