Having Andy chew on the babies receiving blankets

We are trying to have Andy not chew on his shirts and use the babies receiving blankets instead. We ask him not to chew on his shirts, and don't put the bibs around his neck anymore. The bibs on his neck, just promote him chewing his clothing, and they get his shirt soaking wet underneath. Since we are using burp cloths less and less for the baby now, we are letting Andy have them. He was keeping himself busy with a cloth while we were closing up our camper for the winter.
