Oh, no, I didn't mean leaving the bubs in the car! I meant bringing them inside in the car seat. But maybe that is not what they are designed for: just to be left in the car full stop, and now I think I get the argument about the baby capsules because you can pick up bubs from the capsules and bring them inside if they're still sleeping but not if they're in the car seats, as they have to be removed and therefore woken up. I am learning stuff - I think! Hee hee.
