E is almost 11 months old and is BF on demand, but lately the frequency has just gotten ridiculous. He does one really great nursing session in the morning (both sides), and before bed. Then during the day he wants to constantly be latched on. Like...several times an hour ("drive-by nursing").

He'll be playing, then will come up and try to pull my shirt down. I'll tell him no and redirect him (because I don't want to get into the habit of doing it and then doing it in public) and after a few minutes I'll offer. He'll nurse on one side and squeeze the other nipple, then switch sides. Over and over. 3-4 times an hour.

Is this normal? Should I try to be curtailing this behavior somehow and put him on a more structured nursing schedule? I think he's getting enough to eat, but I feel more like a cow than I ever have...
