Hello! DD is one and I really need to buy her the next stage up car seat now as she fills it. I've been into Mothercare and it seems to make sense to get one to last all stages (price wise) - they said the only negative to this is is we change cars they are not all compatible etc. Surely it's just a case of only picking a compatible car if we were to change? Hoping current car lasts us at least 5 years so would potentially only have one change. In terms of actually picking a car seat - where do I even start???
