I have 2.5 year old twin boys and am experiencing similar issues. Is your boy twin talking much yet? My twin boys are not talking as much as my twin girls were at that age, and I believe some of their tantrums and screaming are the result of frustration over not being able to communicate better and get their point across. If your boy is not talking much, let me know and I can go into more detail on how we are handling the issue. You will be in a situation much like me soon; I have my boy twins when my girl twins were just 3 years old. Good luck.
