The simple fact that you're concerned about being a good mom speaks volumes about how great of a mother you are already.
If you make a concerted effort every day to not become your own mother, you're already leaps and bounds ahead.
Personally, I prefer to stick with my instincts regarding my kids and how we rear them vs. books from "experts". If it were easy to raise a child according to a book, we wouldn't have as many different approaches and philosophies as we do and as many kids that get off the right track.
So, trust yourself, admit when you make mistakes.
Remember that education comes in many different forms. Our kids are almost 4 and recently 2. We stress education, but we try to have fun. Going to the library to get books has become a treat, and we give them liberty in what they select. We read, we talk about colors, we ask what animals do, we talk about minute details in movies, we talk about manners.
Last night, we told our son that we'd gotten invitations for his birthday party, but we asked his friends not to bring presents this year (he really doesn't need anything, and not everyone can afford to). We told him that the greatest gift someone can give you is friendship. He nodded and said yes. He'll have a great time being the center of attention, and I honestly don't think he'll notice that there aren't gifts except those we give him.
My only other advice is to remember every day that our job as parents is to make our kids into independent, productive members of society. Don't forget to tell him how much you love him every day and how thankful you are for him to be in your life. Do what's right instead of doing things based upon what other people may think of you. And, realize that you WILL make mistakes. We all do because we're all really learning to be parents, too.
Good luck.
