A baby doesn't want to look at and touch the very same things day after day after day any more than you would want to watch the same movie every day for a year, or sit in the same place in your house all the time. Sing different songs with him. Play different finger games. Change what he can see in the bedroom sometimes.
A rich world for a baby is similar to a rich world for anyone else. A baby is a person. A lucky baby has an adult partner who understands that.
