I bought these two books from book depository.com. Both are highly recommended by friends.
I usually read (if I am not that tired) when baby is napping since she naps an average of 1 hour each time in the day (3 nap times from 9.30 am - 6 pm).
On a separate note, baby has called 'mamama' and 'ah mama' now though she probably doesn't know what that means. Whenever she said that, I am attentive to her so she could be using mamama to anyone to signal for attention.
