Nadav loves a good tissue. Actually, any tissue will do. He's not quite crawling, but when he spots an unattended tissue on the floor, that kid scootches so fast he's got little fast cartoon lines coming out of him. He likes to crumple it, then shove it in his mouth until it starts to dissolve.
Now, I know you're probably thinking I should take the tissue out of his hands. Or his mouth, if it's gotten to that point already. But, you know, when you forbid something to a child, it just makes it all that more enticing. Before we know it, he'll be grabbing tissues when he thinks we're not looking; then it's just a slippery slope to sneaking out at night to score some tissues or hoarding them when he's at a friend's house.
So I think it's better to let him have some tissues here, in his own home, where I can supervise the grabbing and munching. I don't want to think about him loose on the streets, scootching around, frantically searching for a tissue.
