What you are describing to me is typical behavior and I think it is just a phase- well, if handled properly. My boys are 3 years apart and they always want what each other has/picks. That is normal. However, you should not always let her have her way to avoid tantrums. Her twin will become resentful eventually, plus that is not how he should be treated. Secondly, your daughter will learn that if she throws a tantrum (yelling, screaming, refusing to eat, refusing what you want her to do, etc) she will get her way. You need to nip this in the bud right away or you will have a huge issue on your hands in the months to come. She needs to learn that she cannot always have what she wants, and she needs to share. So, I would suggest that you stand firm and be consistent. If she won't eat without her twin's fork, then she won't eat at that meal. Keep offering the meal if she is hungry, but if she doesn't eat it she won't starve herself. If she is hungry, she will eat with whatever fork you give her. She needs to learn that you are in control, and to share. She's not a perfectionist from what you are describing here, she's just a typical 2 year old.
