I could have posted this thread!!

DS2 got bitten about a month ago at CC and has since been biting DS1, he actually on weekend for the 2nd time left teeth marks and drew blood.

He does not do this at CC it just seems to be his brother and is generally in frustration!

We have tryed putting him in his cot, removing him from situation and not letting him have what ever he is after from his brother,

I do not agree with spray bottle as that reminds me of us spraying dog to try and get it to stop barking.
