Melinda, Nick went through the exact same thing, in reguards to the whinging, we used to sit him down and talk calmly to him until we could understand what it was he was trying to say, apparently if you try and figure out what they are saying,they don't get so frustrated with themselves.
The hitting, well that was another story, it got really bad, he only ever hit me or his dad, but it was beyond a joke, we also tryed to get him to understand that hitting is wrong, it took a while, but eventually he took it all in and he doesnt hit us anymore, he just headbutts anything in sight :shock: If it's not one thing it's another.
