Hi my first post today. I hope someone can help. We have had a maxi-cosi pearl car seat for just over a year and my 2year old can open the safety harness. Whilst we have told her she shouldn't get out I'm not happy that she can do this and until today was unaware this was becoming the norm. I was most disappointed with the feedback today when going into the store I purchased it from to be told talk to my 2 year old! I'm not about to put her in charge of her safety. I telephoned halfords who were most helpful and said mums net give great advice about additional safety devices to stop the child from releasing these safety harnesses. Any advice or alternative car seats, please. Thanking you in advance.
