Dd1 is 2.10yr old and is 16.9kgs, she is in a maxi cosi priori at the min and could stay in that till shes 18kg if I remember rightly, but I need to move her into a different seat as shes quite tall and her head is over the top of the side impact wings, and dd2 could do with moving up into it now, so off I go to halfords for some advice, where an assistant assisted me by grunting just stick her on a booster cushion, much easier, and they are on special offer
Most seats I can find online for her weight seem to be high backed boosters, where she would be restrained only by an adult seat belt, which I think she is too young for (prepared to be told im wrong btw),to keep her in it I would have to sit in the back to make sure she wasnt escaping, and even if she stayed in it, would she be safe in an impact?
One seat that I think might be ok for her is the britax evolva 123 which is a high backed booster with a harness, but I think that the harness can still only be used up to 18 kgs after which she would still be held in by only the adult seat belt, I think?
So, what should I do, keep her in the maxi cosi until she hits 18kgs, and buy another seat for dd2 (well another 2 actually as need 1 for our car and my mums) or, buy 2 britax evolva 123s for dd1, or 2 britax evolva 23s (high backed booster)
or, just walk everywhere till they are old enough to use adult seat belts
