Just few moments ago my 2.5 weeks old daughter when laid on her belly (she always liked it and even slept with hands reaching my neck) started to cry a little bit and started flexing. She stared to raise the whole lower part of her body almost to the position like this one http://66.media.tumblr.com/tumblr_m5sayaVGfj1rxfzlmo1_1280.jpg but with chest still attached to mine. Just like she was trying to do a handstand. It looked really creepy but this is not what worries me. This just doesn't look normal to me. This is my first child so there are many surprising things, and I never panicked but with this one I feel a bit anxious, mainly because I had some balance problems in my late 20ties and I am still undiagnosed (so there is a limited possibility that this exotic condition is genetic).
What made me a little bit more nervous is that I tried googling (newborn trying to do a handstand, newborn pincha mayurasana) and to no avail. Maybe I cannot into google as I am not really sure how to phrase the question in my native language.
After being picked up by my wife she calmed down and I haven't tried putting her on belly since - I don't want to cause pain to my daughter just for the sole purpose of "debugging" the child.
I called my mother and she told me to calm down because maybe my daughter is having some abdominal pain and just trying to do all she can not to put the pressure on the belly. And I would be perfectly calm if she would try to roll over. But it's like telling someone that it's normal for a child to start levitating because of back pain (sorry for the exaggeration but I want to you to understand my perspective).
My questions: Have anyone encountered similar situation? Do you think that this is something that requires immediate action (going to hospital) as it may suggest neurological problems or should I wait until next doctor's appointment? This is not a persistent situation so I think it is better to evaluate the situation before going to the hospital (which may cause more harm than good and we still may end up being redirected to a neurologist after classification as not life threatening situation)
Side question: As this is something that isn't easily describable what is the best way to include a video. How to attach/upload it? I want maximum privacy (the less media of my daughter online the better) so maybe some time limited hosting but then if someone else will encounter something like that in the future these is no reference. I want to be decent (I try to be naked for skin on skin contact) so should I use some blur on my lower part of the body or it would still be considered indecent. The blurring is also related to faces (privacy) ofc.
