I am a new mom and i think i am over spoiling my daugther. how to prevent it?

Depends on the kind of spoiling that you do. If you're spoiling your daughter with time and undivided attention, by all means, don't stop. If you're spoiling your daughter with material things, it's a different story. Learn to say no. Give a firm NO. Believe me, you are doing your daughter a favor. You're teaching her a principle that she couldn't get all things in her favor. It's a life principle she will thank you for when she grows up.
