Reading to your babies is a fundamental part of their brain development. It teaches them on how to communicate and express themselves. I kind of actually feel guilty 'coz I only started to focus on reading to Miracle when she was about 1 year old and 10 months. But shortly after I started doing so, I felt so amazed how she suddenly experienced this thing called "vocabulary explosion" where she learned many new words in just an instant. She even suddenly memorized and get herself familiarized with numbers. I made it a habit to read to her daily after that.
