My boys are 14 months old and are getting increasingly more aggresive when one has something the other wants. The smallest especially will snatch things off his older brother and bite him if that doesn't work. The older one has started to bite back, but also often just lets the younger one take things off him.
In the interests of fairness, I usually replace the stolen toy with something else, if there are no tears. But the biting is a different matter. At the moment I am picking up and cuddling the injured party, and ignoring the biting completely, but I'm wondering whether I shoul also be saying 'No biting!' to reinforce the message? What did you do with yours when they went through this stage? (It is common, isn't it??) And how long did it take? We have an au pair at the moment, and I need a very clear plan for her to follow, as I'm sure she thinks I am way too lenient by not smacking my child's hand for biting! (when i told her I wanted her to ignore the biter, she said she didn;t think that was a good idea!)
