First of all, when you begin teaching your baby to read, you must be willing to invest time into the program.  You cannot expect your baby to read overnight.  The most important thing you can do is give your child the opportunity to see language unconditionally.  That means that you will not ask your baby immediately to choose between two words or read out loud for you.  I recommend that you lovingly expose your child to written language for at least six months before you question what they know.  

Nobody likes to  be tested and children can sense when we are testing them.  They can sense our disappointment if they get the answer wrong.  If however, you lovingly and freely teach your baby to read, without asking for proof, your baby will trust you.  The bond you create with your child will grow stronger and your child will either demonstrate on their own that they can read, or when you finally play some games to find out what they have learned, they won't mind playing.

The best way to sabotage your baby reading program is to not trust in the process and constantly drill your child.  For this reason, it is better to start teaching a 3 month old to read than a 2 year old, because we are less inclined to ask our infant to prove what they are learning.  Babies that were taught to read as infants often begin speaking and reading orally at around the same time.  They have experienced many months of reading words without being asked to perform and are more willing to share what they know than a child that is being drilled or asked to show off their new skill.
