Weird? Extended BF & PG

cyprissa

So I still nurse my DS at bedtime and once in awhile in the AM. I haven't really noticed any major changes in my breasts or supply...until now.

I have always had a better supply in my left breast so when we dropped down to once a day, I was just using that one and haven't fed on my right in about 2 months. Well, this week, righty (the boob formerly known as the Milk Dud) has started filling up with milk. Is this normal?
