Sibling gift

So I read online that some people do sibling gifts for their kids for when they met for the first time. I really love the idea but was wondering what you would get. I have a daughter who will be 2 when baby comes. I was thinking her sister "would give her" a doctor set because she recently found our first aid kit and loves playing with the thermometer and medicine cups. I know she would be super excited about this and it would help distract her from the fact mommy isn't paying as much attention to her. But I was wondering if I should get her, her own baby so she can be like mommy or do you think I should do something totally different?
