Hi My dd who is 2.5 has became a monster seriously . when my ds was born she was great always wanting to help with him and look after mummy but now he is 7months and starting to move about she hates him punching him kicking him and even attempting to throw him across the room he isnt a small baby hes in 12-18mnths clothes so quite heavy she even wrecks my house if she doesn't get her own way and trys to attck me she has been going to nursery since june so she is interacting with other kids i have tried naughty step but that became a game to her then sending her to her room also a reward sheet with no success i give them both equal attention and spend time with her on her own she also hates the fact i have just went back to work but she is a angel for her dad behaves even helps tidy up and play with her brother this has really got to me andi feel completely useless
can anyone help with some advice on how to control her behaviour i really dont know what to do i have tried to ignore it but that makes her worse i do understand she is only a baby but she understands everything else so she quite a clever wee thing
