firstly not Jack he is one of the victims

2 of Jacks little firends have started biting again they both did it about 6-10mths back but then they stopped now they have started again

I had a little party monday with 3 of jacks friends the little girl and Jack were both left with at least 3 bite marks each

the 2 little boys (may 06 born and July 06 born) did bite each other but didn't seem to make a difference

one of the little fellas (may) it is usually when he wants something he reacts by biting first then shoving

the other just bites it seems he bit Jack again yesterday

now I love these boys they are lovley excpet for the biting I feel so sorry for the mums as they seem at their wits end with it, and mortified their boys are biting

so what I need is some suggestions on how to help the mums deal with the biting issue
