Have just shelled out a great deal of spondoolies to get a cybex solution x shipped over from Germany for 4 y/o dd, as we haven't got a car so every time we go in one she falls asleep immediately and her head lolls, and so thought this was te best one for her as her headrest tips back, stopping the loll. However, have been left a car in a will and have my driving test next month, so we will be more mobile soon-should I have got an isofix seat instead? I worry about how flimsy and un-anchored the group 2/3 seats are.
