Yes, the more interaction you and your wife have with your child, the better!
Babies are learning at a phenomenal rate, and the more stimulus they receive, the more they are able to pick up about the world around them. Studies have shown that there is a link between parents reading to young infants and reading habits:
Shared book reading at 4-months was not predictive of later expressive language, but it was related to shared book reading at 8-months, indicating a reading habit can be established and persist until the infant is more ready to benefit educationally from shared book reading.
Increased interactions with your child help teach the infant to recognize you and your wife. These interactions will also lead to your child giving their first true smile sometime over the next few weeks, and trust me: that is not something you want to miss! :)
Touching and massaging your child regularly can have significant benefits.
Even though you aren't going to see huge levels of response from a 2 month old, the more you interact, the better you will become at recognizing your child's body language and other cues as to whether they are happy, content, hungry, uncomfortable, or just plain bored.
