Anyone got some bright ideas to stop my dd (3.8) falling forwards out of her booster seat when she sleeps in car journeys - it looks really uncormfortable and I'm sure it cant be safe! Went to a lot of trouble to get a decent booster seat, and snce moving her over, had this trouble - wasn't posible when she was in the 2nd stage seat as it had a 5 point harness! Does anyone make a restraining device for this? I have tried those cushions that go around the neck but she doesn't like that. Help!!
