They seem to lack any skills of behaving especially in public. For example we go to a cafe,one keeps walking around even tho asked to sit whilst eating his ice cream,the other sits beautifully whilst eating but proceed to jump around "like a gorilla" and try to climb on furniture.ignoring any telling off from myself.so we were there all of 10 min and they couldn't be good for that short time.then 2 year old starts screaming so decided to leave.I'm feeling down about it all,I have to shout their name so many times before they even answer,tell them to stop/not to do something is just ignored. We use time out(but never really been that effective)and take away screens etc but nothing changes.friends tells me all kids are the same,but are always mine the ones to misbehave all the time.and they can be very aggressive between them,7years old will hold his brother from the neck if he annoys him.feeling like crap at parenting.
