Thank you so much for the responses to this post and to Mel at Stirrup Queens for choosing it for the Roundup. I feel really supported by the comments and I'm glad it resonated with so many of you. I actually didn't receive one flame comment, and for that I am truly grateful.
Only a few days after I wrote the last post, my chin went back under water. I must have jinxed myself, because just when I thought I was feeling secure, I lost it. There were entire days I spent crying. There were moments when I literally felt numb as I walked through my day. There was a week-long visit with my sister (and a blizzard!) that I was only half present for. There was a dinner with girlfriends that I held back tears through. It was during that time that I realized that PPD is going to be with me for a bit. It may not be there every day, but it's standing right behind me for now.
It seems that my mood is completely linked to how LF's day goes. He recently got diagnosed with reflux and now that we are treating it, it seems as though a lot of his crying, irritability, and fussiness was linked to it. Poor kid, no wonder he was so difficult to soothe. But, in the days (weeks) leading up to his diagnosis and for several days after we started medication, he was inconsolable. He cried on and off all day and night. He slept fitfully in short spurts. He was just in constant need, and I felt like I was failing him because I didn't know what was wrong or how to help. I was a mess. He was a mess. As you can imagine, this made life incredibly stressful in the Fabulousness household, and poor KG was left to pick up the pieces.
Since getting treated, he has been much more comfortable and therefore much easier to soothe. KG and I are also figuring out more about him as a person - his cues for fatigue and hunger, his need for swaddling when he's overstimulated, and the difference between his cries. I've even managed to get him to take more naps (although he only sleeps for 30-45 mins at a time). Now if we could get him to do longer stretches overnight, THAT would be something (Advice about 7 week olds here please?). He also found the beginnings of his smile (a bit late) and is starting to focus on our faces more. Finally, I am starting to see my little man's (complicated, cute, fussy, funny) personality, and therefore I feel a little more secure and grounded. More frequent visits with my therapist and a tweak to my medication have also helped push me in the right direction. Not to say that there aren't bad days, but, on his good days, I feel optimistic.
