I am the well organised type and I love to be prepared in advance for everything. That is kind of opposite to my partner who is sorting things out 15 secs before the last deadline... I do not want drive my little love even single yard in unsafe environment so I want to buy a car seat in advance. The problem is that my baby looks a little bit larger than standard. I can afford to buy some clothes and give them for charity if they don't fit but I don't want to spend 100s of pounds on the car seat and giving that away after couple weeks. Buying too big is not solution neither as it could cause more harm than not having that at all BTW The market prices differences are huge. I want to go for possibly the best. But does it has to mean the most expensive at the same time ? Let me know what do you think.
