Meet Erin, Owner of LMS Chicago

updated, March 15, 2026 - Meet Erin Thomas Walker, a successful business owner and mother of three. Erin’s compassion and deep understanding of working families keeps her genuinely connected to the families Let Mommy Sleep serves across her growing network of territories.

Since Erin opened Let Mommy Sleep Chicago in May 2020 — in the middle of a global pandemic, with a toddler and an infant at home — she has expanded her licensed territory to include Detroit, Ann Arbor, Ohio, Wisconsin, and Indiana. She has also had another baby girl since opening. Read more about Erin’s story in Thrive Magazine.

About Erin

As a mother of three with no nearby family, Erin has a personal understanding of why postpartum support matters. What started as a search for trusted overnight care for her own family turned into a passion — and then a business. Her background in high-level banking and real estate investment gives her the organizational discipline and energy to run a multi-territory operation while staying genuinely connected to the families she serves.

Erin also truly enjoys supporting new parents who, like their babies, have also just been born into a new role. As Erin puts it: “When you do what you love, they say you never work a day in your life!”

Erin has since become an expert postpartum doula and breastfeeding peer counselor in Chicago.

What Erin’s Story Means for Prospective Licensees

Erin did not come from healthcare. She came from finance, built her first territory during a pandemic with small children at home, and has since expanded into five additional markets. Her trajectory is one of the clearest demonstrations of what the Let Mommy Sleep licensing model enables for the right operator. Meet more Let Mommy Sleep owners. 

A Day in the Life — In Erin’s Own Words

This morning I woke up to a loud, “Yeaaah!”

I opened my eyes and looked at the clock. It was 6:45am. This is way too early, I thought as I glanced at the monitor, assuming to see a baby happily awakened from his slumber.

Oh crap! There was no baby! I jumped out of the bed and raced down two flights of stairs to where the Yeeeahhh alarm originated.

I was moving so fast that I lost my balance and slipped down the last stair, falling through the baby gate. Carter, my 3-year-old, startled by my entrance, screamed and slipped off the trampoline as I landed hard on the playroom floor. That’s when I realized that this little boy escaped from his room, hopped ALL of the baby gates, and threw himself a baby party! The TV and the lights were on, the couch pillows were on the floor, the toys were scattered about, even the toilet seat was up (lort!).

“My back hurts,’ I thought to myself. It was only 6:45 in the morning.
