Struggling out

Clarence can sit in the bumbo chair for a long time and won't even bother to struggle out when he was a baby but Mei mei is the opposite. She has been trying to push herself out for quite some time. Judging the way she is pushing, I think she will be able to get out of the bumbo chair by herself soon. Glad that we did not invest in another bumbo chair for her or else it will be rather wasteful if she doesn't want to sit inside.

Sad to say, she succeeded today! I saw her coming out of the bumbo chair twice. Why is this small sized girl so strong?
