My husband and I moved oversea 8 months ago with our 3 year old. 6 months later we had twins. Needless to say our first born is feeling deprived of attention and has become a pain to live with. Do these transitions merit any difference in parenting skills? She is on the ticket system a week, but today while she was in her room she ripped a book, so I took all of her books away. Am I too harsh?
