I've been having increasing problems getting my 2 year old daughter into her car seat and then staying in it. It sounds trivial but it is so stressful as it is such a battle and she gets herself in a terrible state. Also the more stressed she is as we set off the more likely she is to wriggle out of the straps. It got a lot worse after last weekend when the car was so hot but it is continuing now its cooler. She's the same if my husband takes her in his car.
I've been considering the "naughty step" if at home but hard to do if out as nowhere safe to leave her. Also sticker charts for getting in and staying in, but do you think they will work at her age? (only just 2).
