Need a carseat for DD who is 14kg (almost 3). I can eke out the current one if need be but it's old and looking a bit grotty. 3 kids in the backseat; one is a high back booster, one in the middle who can go without a carseat now as he's tall enough. We don't own a car, we just rent and it changes every few months; sizing varies from about a peugeot 108 right up to a big 7 seater SUV, so we don't want a car seat that's too wide as who knows if we'll get everyone on the next car we have otherwise.
I'll be likely buying online (EU) as variety is a bit limited here (and more expensive), so i can't necessarily see them first. Any recommendations? She gets carsick so not sure if rear facing is helpful.
