After I nurse I sometimes feel this wave of sadness. I have no problems with latching, he's growing like a weed, and for the most part breastfeeding is not painful. The sadness isn't related to any pain or discomfort. I probably feel the sadness a couple of times a week, and it's usually related to marathon feeding (feeding from 45 min to 1 hr) sessions. I'm pretty sure it's related to some hormonal change.
The little sir is 1 month old.
The only articles I've seen shows how breastfeeding can help alleviate PPD, but I'm wondering if there are any cases of the opposite.
