hi J.-
biting is a tough phase for one to go through, but remember- it is a phase! you didn't say where your son is while you work... is the biting happening only at home or at a day care too? I work in a preschool and we recently had a toddler who was biting and here were suggestions from our health nurse:
1. have your son visit the dentist/doctor for an oral exam. we've usually thought to wait until 3, but some pediatric dentists suggest starting as young as 12 mons. the dr. can check to make sure everything is 'normal'
2. is he just biting you? this would be attention seeking behavior - so try to committ to some quality time 1:1 with him. give attention to the positive, immediate consequences for negative. (ie- give attention to the 'victim' of the bite, while turning your back on the 'biter')
3. sleeping - is he getting enough sleep? i think many behaviors (biting included) mask the issue of not enough sleep!
4. does he have an opportunity to play with children his own age? if so, is he biting them? does he play appropriately (as appropriate as a 14 mon old can!)
and lastly- never bite a child to biting! what message is that teaching him- especially at 14 mons he doesn't comprehend what you're trying to 'teach' him. he just knows that mommy bites, so he'll bite too! good luck!
