I remember 2 or 3 yrs ago my LO was crying intensively when carry her and realize she had difficulty in pooing. In the end, we laid her down on the table and look at the anus that the poo was stuck at the entrance. I was so panic that don't know what to do and lucky thing was my hubby was with me. We did not use finger to pull it out. Instead my hubby hold her leg open n close, straighten and bend like what karoosel mentioned. In the end, the poo did came out. The poo was big that's why it stuck and unable to release. That was one of the greatest memory ever since my LO came to the world 4 years ago.
