DS (19 months) hates getting into the car in the morning and cries with great gusto when we put him in. This morning, he passed out - he was limp and his eyes closed, and it lasted for a minute or so before he came round again. I didn't have the composure to check whether he was breathing or not. It happened about six weeks ago at his nursery, too - the poor assistant who was with him said he did stop breathing and was a nervous wreck afterwards and now I can see why.
Has anyone else had any experience of this? DH's sister used to do it, apparently. But I don't like it at all.
