Is this crib made of ... wood?

My son has just about ever single dodad that Target, Wal-Mart, and Babies R Us sells for teething babies. Everything! However, their not good enough for him. He'd rather chew on blankets, bibs, straps, belts.. ANYTHING! Now we can add another thing to that list. HIS CRIB! I hope this is safe, because my little man has been chomping away at his crib!



oh and books!



and stuffed animals!



Nursery items beware! Because who knows what's next!!
