DS is a big boy. He will be 2 in a few weeks, but he is too big for his car seat. His head is above the height of the seat and the straps at their most adjusted are about a 1/3 of the way down his back. I popped into Halfords this morning for them to check it - they said his head wouldn't be protected from side impact as he was too tall, and the straps should come from above his shoulders down the front of his body. As they are they could cause damage to his shoulders in an accident.
He isn't yet 15kg, so isn't heavy enough for the next stage car seat but I was told he would be safer in one of those rather than the one he is in now, so that is what I have bought. Is this right? Also how on earth am I going to kep him in the seat?
