I remember leaving the house before sunrise the morning I gave birth to my son. My daughter, just a toddler at the time, lay sleeping peacefully in her bed. I felt an overwhelming sense of sadness as I pushed her hair back to kiss her goodbye.

She had been the center of our world since her birth, and I couldn’t help but feel I was somehow betraying her by having a second baby. Would she feel like she wasn’t enough for us? I choked back sobs as I heaved my pregnant belly into the passenger seat of the car.

“Honey, it’s going to be fine.” My husband did his best to reassure me. “She will love him, just wait, you’ll see.”

Now, almost three years later I have to give the man credit, he was right. In the famous words of Forrest Gump, my kids are like peas and carrots—one doesn’t go far without the other.

Of course they still squabble and bicker with each other, they are siblings after all, but they spend most of their time playing, laughing and being silly.

The other day, as I walked down the hall of my daughter’s preschool, I noticed a colorful display of artwork. Being the proud mother that I am, I stopped to find my daughter’s masterpiece. Each child had drawn a picture with a corresponding response to the statement, I am thankful for…

I scanned the wall until my eyes came to rest on my daughter’s creation. Two clumsy stick people stood side by side, and written below them, in large, uncoordinated print were her words, “ I am thankful for… my brother.”

I felt the back of my throat tighten as tears brimmed in my eyes. I never thought I would be the mom standing in the hall trying not to cry over preschool artwork, but there I was. Such an honest display of love for her little brother—exactly what I had hoped and prayed for the morning of his birth.

Just then, from the doorway of her classroom, she spotted me in the hall. “Hi, Mommy! Do you like my picture?” She beamed up at me proudly.

“I do, honey. It’s absolute perfect.” I said as I reached down to hug her.

I have always known my kids were close, but in that moment I realized just how much they mean to each other.

It's hard to believe I was ever worried. Their love for one another is genuine, honest, and effortless. As their mama, my heart is happy knowing even if they have nothing else, they will always have each other.
