On the way to collect DD and baby from hospital, we had to stop at Mothercare to get someone to show us how to disconnect the infernal thing from its Isofix base. We had been trying for the best part of an hour at home, having clicked it into place so easily. Neighbours popped out and had a go, passers by tried, but no, it was firmly stuck.
We were panicking because we understood that if we didn't bring the car seat into the hospital they wouldn't let the baby leave . (This turned out not to be entirely accurate - they would allow the baby to leave as long as they were satisfied there was a car seat in the car).
The Mothercare staff member popped down to the car and effortlessly removed the car seat, much to our embarrassment. We had, apparently, been holding the thing the wrong way - a quick lesson and it was as easy as pie .
That was nearly 4 months ago, and we've only just worked out how to loosen and tighten the straps while the baby is in situ. So finally, it is much less stressful than it has been.
