My b/g twins are 19 months old. They constantly want what the other is playing with, pull hair, push, pull, hit, scream, bite etc etc. When we go out to groups or friends houses they often get into everything so I find myself up & down checking on them. I am exhausted with it & have been in tears tonight. I have been doing a mini-supernanny discipline technique but my boy just laughs at me whereas my girl seems to understand. I then tell them what they did waswont good behaviour & ask them to give the other one a kiss to say sorry. But, I am now thinking of changing the discipline to praising good behaviour & ignoring the bad. Has anyone gone through twin sibling rivalry? I am at my wits end with it!! I also have a 5 year old who Asks me to p,at with him but I often do not get the chance. Help!
