Hi Marek,
I have to say that most post on the web are pretty short on absolute answers. The information all came in bits here and there from the various sites that could be found.
Here are a few :
Baby stuff (pretty generic) :
10 Tips for Photographing Babies
Lighting setups :
Photography and blog about studio lighting setups by Alexey Ivanov & Julia Ivanova
Neil Neikirk's site (I love his photos/examples/approach to lighting) :
http://neilvn.com/tangents/flash-photography-techniques/
Of course there is Strobist :
Strobist: Lighting 101
Most inspiration comes from trying to pickup/copy what baby photographers do :
Really like Kelly Ryden's works :
Omaha Nebraska Newborn Baby Photographer Photography
Simple setups and lighting, but so gorgeous.
