It's no longer enough to put down a sheepskin for him on the floor. There must be a large blanketed area to have any hope of keeping him off the filthy floor, and even that's not always a sure thing.
He spends a lot of time on filthy floors. I tell myself it's good for his immune system. Ahem.
The real area of concern with his semi-mobility is near the woodstove. Obviously, I do not want my infant son to be rolling himself into our blazing-hot woodstove. But he does so enjoy rolling about on the warm floor near the stove.
Luckily, we have an inconveniently large dog who also enjoys baking in front of the woodstove, and she serves as an effective barrier to baby burning.
Of course, sharing a blanket with a dog kind of negates the cleanliness aspect of the baby on the blanket, but it's better than first-degree burns.
