(sorry couldn't find a logical place to post this)
Not a 999 emergency (obviously), but a "need to take child to hospital with broken arm" or "rush back to help unwell family" type emergency, where taking the bus/train would be difficult. Obviously a taxi would be needed.
We do have a small car (VW UP!) which DH can drive (I can't currently due to medication) but he is not always here due to work (often hours away or abroad). So we will need a car seat that both fits in the back of our tiny car, is ideally rear facing for an extended time, but also suitable for use in taxis (so probably not ISOFIX?). Does it exist? Also, if taking a child to the hospital, I'd then have to lug a huge car seat in/around as well as an unwell child, wouldn't I? Argh! I so wish I could drive. What do other people do? Please tell me I'm overthinking this.
My mum lives 45m away and is retired (but young) so could in theory drive to pick us up then on to the hospital/wherever we need to go, but I'd prefer not to be so reliant on my mother!
