Have Maxi Cosi Tobi carseat. DD, 19 months keeps taking arms out of straps whilst I'm driving. Obviously I'm concerned about her safety. Yesterday, I noticed she had done it almost straight away and stopped the car and fastened her back in, today I didn't realise until we got home. I told her off but I'm pretty sure she doesn't understand that what she is doing is very serious. I'm not very confident at disciplining anyway. Anyone have any solutions to this?
