Re: My 24mo has not nursed in 4 days, but I still have milk!
I could still get a small amount of milk for about 6 months after weaning. A year post-weaning is not uncommon and >1 year is less common but still not out of the ballpark.
Since the weaning was gradual, you probably don't have to worry about infection. But do stay vigilant for a while. If you're going to come down with something, now is probably when it would happen.
