Do you do some kind of reward at the end of the day or end of the week if your LO behaved well for you? I think that would be our answer to fixing our DDs new bratty (talks back, never listens, lies to us now) behavior, but I almost feel as though I'd b bribing her to be good. What are your thoughts? We do time outs and if she doesn't go into time out we do a spank. It doesn't stop the behavior, it just disciplines her and she just goes back to being mean and nasty. She has a new baby sister (5 weeks old) so I know why the sudden behavior change.
Re: rewards for good behavior for 3.5 year old...
That being said, at 3 or 3.5, DD had a potty training regression. Dry panties at school earned a sticker on the chart. 5 stickers earned ice cream, 10 a trip to Chuck E Cheese, 15 a trip to the zoo and 20 earned a private tour at Global Wildlife (a local animal sanctuary where you can ride in wagons and feed the animals from the wagon).
We always get his input and remind him in the morning what he is working towards.
