This morning my son (25) came over to breakfast and told me a story about last night.
A friend, friend's gf & 3 year old girl had come over to his place. It wasn't the first time. Mandy, the 3 yr old, kept playing with his computer & xbox, even though the gf/mom had told her to "stop that" several times.
Finally, my son had had it. He walked over, picked up Mandy. The mom piped up then asking him what he thought he was doing - he gave her a dirty look, held up his hand and said My house, My rules, My call.
He asked Mandy if she knew she shouldn't be playing with his xbox. She said yes, but wanted to anyways. He told her that it was not allowed at his house, no matter what she wanted. He put her in timeout (yep, mom was having a fit - my son told her to shut up). When the timeout was done, he asked Mandy what she did wrong. She told him. He had her promise not to do it again and to apologise to him. Mandy did and hugged him. Mandy also didn't play with computer or xbox again.
GF/mom was amazed. My son told her to try talking TO Mandy - not at her and to stop her if she was doing something wrong..
HE THANKED ME for showing him what to do. Thats what I did with kids in my home..
