M.F.
I have a mirena iud also and have a baby a little under a year too. I have not changed my nursin pattern purposefully but with more food and stuff my daughter eats more infrequently and I have been noticing the exact same thing. I've had it before briefly but not prolonged! Now I am curious since you have the same issue. No answer here just empathy and the hope that if here's more than one that there is nothing wrong. If you do ask your doctor I'd be curious.
