Hi... were due first baby in march and have most things sorted but i got a car seat with a pram set and it's really awkward to install into my car and seems a bit flimsy.. it's a roma 2 if that means anything to anyone and i have to pull the seat belt around it to keep it in in bit its seems insecure and wobbly! .... the question is.... do i buy isofix base and will any base fit? Or is the car seat crap do I get a new one? Any advice appreciated...
