I think @deworde has the best advicethe best advice to help motivate you to read stories. However, I wanted to add an answer that mentions options other than reading.
Until they are about six months old, babies will rely on tone of voice and sentence patterns to help learn to understand you.
The more you interact with themmore you interact with them, the better they'll be able to learn how to understand you.
So don't just limit yourself to reading stories. Have "conversations" with them. Tell them about your day. Explain what you are doing, and why, even when doing routine chores. Sing to them. Tell them how much you love them, frequently.
Consider proper useproper use of "baby talk" when talking to them.
