What do you think

The first picture is of my third child. I have concerns about this picture and wandered if anyone else would as well. To me the leg looks curved I don't see a bottom but see 2 full blown balls. The last 2 pictures are of my other son already born. What do you all think anything for me to be concerned? She did not double check the bottom area or anything like that we never even saw our whole baby in a picture.
