I have a 4 year old and we have really been struggling a lot with his behavior. In the past, I felt like he would act badly for us but them would act sweet and perfect at school, around family, etc. However, today we got an email from his teacher that he's becoming a problem at school (disrupting circle time, going to the thinking chair, etc.). Time outs haven't really worked for us lately. If he is put on the couch, in his room, etc., he will just try to destroy whatever he can by throwing pillows, spitting, etc. We have also tried taking away toys for 24 hours, which he finds upsetting but doesn't really stop him from repeating his behavior the very next day. We're planning on taking away the iPad starting tonight until his teacher reports his behavior has improved but I'm kind of skeptical that it will really do much since he is only allowed to use it during breakfast as it is. I'm just wondering how others deal with the talking back and behavioral issues at this age. I feel like what worked at the toddler level isn't really working at the pre-K level. Does anybody have any great book recommendations on discipline? I should also note that I'm pregnant and due in about 7 weeks and he's very anxious about the arrival of a new family member that will take attention away from him. Some family members think he's acting out in relation to the upcoming changes but I can't imagine he really gets how things will be changing at this point. Thanks in advance!
