at 8 weeks? actually i did told my hubby, maybe his is teething, hee... ok, will check his gums. Thanks Eliza.hahas.. licking for ice-cream?? Just kidding. Clean ur finger and put on his gum to check around if it's hard or best, if there's any white spot. Might be tooth erupting.. If so, get teething gel from pharmacy and put a little bit on the gum.
