OP I don't think what you're saying is abnormal at all. I read some well-regarded parenting book (I forgot which one though) that basically says no parent should be at home for most of the day with small children.
Over time I have discovered that what works for me is the following:
1) Outside whenever possible. A walk to a neighborhood book house. Geo caching. A playground. A hike. Whatever. Anything outdoors is better than indoors.
2) When we are stuck indoors, I do stuff around the house, and the kids either start entertaining themselves, or they help me. Things like laundry, cooking, etc. If they say they're bored, I can say "Oh great! Come help with dinner" and then either come help, or find something else to do
Example: Last weekend when it was raining, I reorganized a closet and the kids were super entertained by the random crap I found in the closet, while I got my project done.
