3yr old and 15mthold behaviour......

[hermykne]

3 yrs and 15mths
3 yr old is so demanding, shouts if i say no, is a total cranky miss and just so unpleasant and not her normal self, to her brother - she has started hitting him or pushing him off "her" chair/beanbag etc, taking everything he has out of his hands even though she has no interest in it. i am exasperated trying to make her understand.15mth old is just cranky too, normally quite happy, but got very clingy this week and just unsettled.

hopefully those with ecperience will tell me this is power for the course!

ps
cranky 3 yr okd has just made me a sunflower out of a piece of wrapping paper i said no to but gave in - how does one cope.....

Maybe its a girl thing. My 3 year old is being nightmare at the moment. Actually shes been that way since the day she was born. She is extremely naughty and laughs at both me and dp when we tell her off. Have tried different forms of discipline but nothing seems to work. Shes very sneaky and crafty about what she does and is often to be found biting, hitting, scratching or generally just bullying her brother aged 4. She loves him to bits and they are the best of friends (only 13 months between them) unfortunately she does seem to take it out on him though. I am hoping it will pass and I am wondering if it is an attention seeking issue.
