Ladies, thank you for all the support and ideas. Stan's best buddy has just left nursery, so Robert is going to stick around for a while at least. The pressure is off on the laundry because nursery FOUND the third Robert, who I had given up for lost, so now we have 3 and not 2, and that helps. The other thing I have been doing is going in once Stan is asleep, and taking the lovey out of his mouth. He doesn't generally put him back in again. Which means that the lovey is getting less gross (it is mostly dry by morning), and he's not spending all night sucking on it. It's good - every time he wakes/stirs in the night he goes back to sleep without sucking, so I'm pleased about that.
