Sometimes it's hard to remember she's only 2

Big sister is equal parts easy and challenging right now. She wants to be independent and can do so much for herself. But she also sometimes acts out when I'm nursing or caring for Porter. She picks the times when diversion is most difficult (she is so smart). And I'm working on being gentle with my reprimands...its too easy to snap or scold when I should be showing her how I want her to act and redirecting her. She talks and acts like a little adult at times, so I need to remind myself that she really is just two!
