Frustration

Mary has been getting so frustrated with her immobility lately. She will intentionally roll on to her tummy as if to practice crawling! But then she ends up getting frustrated because she pushes herself backwards. She can't really get up on her hands and knees yet, but she tries to. In her efforts she pushes up on her hands and tries to get her little legs going but ends up sliding herself backwards with her hands. It's cute but sometimes I have to leave the room. I get so frustrated FOR her! Sometimes I try to help her, but it doesn't usually do any good.
Today I took pictures while she was 'practicing'
