I want to start reading to my child. Any rules? How long should I start reading to her? She is 6 months old. Is it too early to start reading?

Start to read to them as early as possible from small picture books slowly upgrade to short stories then a whole book... I started both my kids since birth even though they don't understand yet. Helps with their imagination, speaking and bonding. Now my kids love to read and bringing them to the library is also good
