What’s it feel like to see your kid finish kindergarten? It feels like… a lot. Here’s what I’d like to tell my 6-year-old now that he’s finished his first year in school.

A letter to my twin four-year-old girls on their birthday.

What would you, new parent, give to have a moment of solitude?

To feel like there aren’t a million things going on?

To feel like you aren’t worrying about what’s going to happen, and regretting all the parenting blunders you just made?

In honor of Father’s Day, Instafather and Flat Circle Blog teamed up to combine our fatherhood and our pop culture knowledge into one special post full of some of our most memorable sitcom fathers. Take a look and tell us who made the biggest impact on you!

I’ve got answers to your questions about fatherhood and all things #dadlife in advance of Father's Day! I was thrilled to do an Ask Me Anything session over at amafeed.com about having twins, what it was like becoming a dad, writing a book about parenting, and more.

My former NICU babies are now big girls turning three... which is impossible because they were just born yesterday. Here's a letter to my twin daughters.

What do others spend on childcare? And how the hell are you supposed to afford it? Let's talk.

What's that weird cough your kid has? What is stridor? Why does everyone keep saying croup? Am I cool? I can't help you on the last one, but I've got answers lined up for croup and stridor after we dealt with it over the weekend.

From starting life in the NICU to running around like two little dynamos, I am running out of ways to describe what it's like having twins. So here's what I have to say right to them as we enter age 2.

When dads get together to talk about fatherhood, there's a lot to learn. Here's what 13 dads, including myself, learned over a weekend of bonding over #dadlife.

I'm embracing taking a step back from parenting from time to time. Are you?

"Why didn't anyone tell us that at some point as a parent, you could be pooping and throwing up at the same time and you'd still have to get up with your @%*&$@% kids at 5 a.m. the next morning to get them breakfast?"

After telling my story of dealing with anger, frustration, and depression as a parent, I've heard from so many of you dealing with the same thing. Let's not let that momentum go. Let's be more honest with each other.
