I am 3 months pregnant and people have been (smugly) asking when I am getting rid of my SLK. I have (had) no intention of getting rid of my car as my husband has a jeep so we have a pratical car, but I would like the facility to be able to drive my car with the baby sometimes. Any advice on how I find a suitable car seat? All the info I have found online is very confusing. Does it have to be a mercedes car seat? They're v expensive for a 'second' seat (and I assume they couldn't be shared with the jeep?) Thanks!
