One of my babies keeps rubbing his face against his front legs, like there is something there irritating him but I can't see anything. At first I thought something may be bothering his legs so I've gently scrubbed them with a new, clean toothbrush hoping that would dislodge or clean off whatever was bothering him. It didn't help. It's been about 24 hours since I first noticed the behavior and he is still doing it. Any thoughts out there?
