My son will be 3 next week, and I remember being in your shoes. He still nurses usually once or twice a day and if we are home he like to nurse before naps. I also get frustrated when I am folding laundry or trying to work on the computer and he takes that as mommy is free I can eat. However there are times like the other day I worked and when I picked him up I could tell he was tired and irritable. I took him home and with in 5 minutes of nursing he was out took a good nap and woke up happy. Plus I got to cuddle and hug on him after missing him from being at work. Times like that I am thankful I am still nursing. Even if the rest of my family thinks I am crazy.
