Thank you - that was my gut feeling, but DH was then saying that as no one was hurt and it was 'only' the boot which was damaged, that they might be ok.
However DS1's was in the boot at the time (he was on a smaller booster) as Granny had been travelling with us earlier in the day and it was the only way we could all fit in, so we hadn't moved him. Although, this turned out to be a good thing because he was in the middle with a proper seatbelt where there was still a headrest so his head was protected.
If DH had been next to him where there wasn't a headrest (because normally DS1's seat is there and it won't fit with the headrest in) DH would have got severe whiplash I think.
I've put headrests on the packing list for next time!
Right off car shopping (I reckon they'll write my lovely old Peugeot off ) and car seat shopping.
I'm in a quandary about whether to replace the DS's car seats.
We had a rear end shunt (causing £3k's worth of damage to my car) on Tuesday 270 miles from home and I'm wondering whether I should get the boys' car seats replaced.
They are Jane Indy Team (or the more modern, can't remember exactly) and we've used them to get us home in the hire car as didn't have any other option, but I understand that the manufacturers' recommendation is that they are replaced.
