Think my boy is teething too. I tried to put my finger into his mouth, he chewed very hard and refuse to let go of my finger. Also very cranky at nite.... Need to be coaxed for very long in order to sleep....I bought a TT teether (maciam pacifier) for him to chew and he likes it v much. As for Sophie the giraffe, he is still learning how to hold it. I find Sophie is abit dangerous as it keep poking my boy's face and eye area.
