Hi,
I can fully understand you want to help your baby as he is in pain, but Aspirin and Tylenol is toxic to cats and should never for any reason be given to them.
I would recommend waiting until you can speak with your vet and seeing if he can prescribe Tramadol for the pain. You can use warm compresses to help alleviate any discomfort your cat is in. But pain relief in the form of human medications are not a option.
I wish your and your baby the best.
Walter
