I read to DS from the time he was a month old... More for my own amusement and because like you i didnt know what to do to stimulate them and help them learn but I think it was a good idea, it got me used to reading stories every night or in the afternoon and we still do it everyday and he can practically read. he actually read a few ( probably off memory) and corrects me if I try to change the story on him if I m not reading properly And hes only 2.5yrs old now....

But you are doing plenty already.... this is the only other thing I can think of atm....
