What about stepdads? Can you offer any pearls of wisdom for the Dads out there facing similar struggles?
Dear Dad II,
From what I've seen and experienced Stepparent struggles know no gender. Stepmoms and Stepdads face many of the same challenges, as you noted, so I hope you've found some solace here since online resources are (sadly) limited.
(Though my Stepdad made it look so easy. He was the coolest most down-to-earth guy who NEVER got his feathers ruffled. I miss him.)
But if you're looking from some places geared just for Stepdad's try here and here. Also give these Dads a shout and see if they can scout out a blogging Stepdad to add to their family.
