Hartley: An Alliance of Moms & Slumberkins Collaboration

Co-founders Kelly and Callie took their connections to foster care and created a creature that speaks to blended and foster families around the world- Hartley. Hartley is unlike any other creature, and Slumberkins donates proceeds to help continue the important mission the Alliance of Moms is carrying out. Read more about Hartley and the “Heart Family.”

We have a very exciting announcement that has been in the works for a while – and now the time has come to say: We’re so happy to introduce you to Hartley!

Hartley is a special Slumberkin, whose story was written specifically for children in blended families, in foster care, or who have been adopted.

Hartley Slumber Sloth

Both of us have very personal connections to children in foster care. My (Callie’s) parents were foster parents when I was a child, so I understand how painful of a transition it can be for both the children placed in the home, and for the family that opens their home, when the time comes for a foster child to leave. Kelly’s own father was a foster child, and she has also worked with children in foster care for many years as a therapist in the Portland Public School District.

In our ongoing mission to give back, we have partnered with the Alliance of Moms to support a cause that you can see is very near to our hearts: foster care. Founded by five LA moms in 2014, the Alliance of Moms is a membership-based auxiliary group that supports the work of the Alliance for Children’s Rights. Their mission is to break the intergenerational cycle of babies born to teens in foster care. (You can read more about their mission, along with some staggering statistics, here.)

For this very special partnership, we have created an exclusive Alliance of Moms Slumber Sloth and Sleepytime Rhyme board book: The Hartley Bundle.

The Hartley Slumber Sloth is an ultra-soft and cuddly friend that, when used as a transitional object, can provide an immense amount of comfort and a feeling of security – to help ease anxiety and transitions for little ones.

The corresponding interactive Hartley Sleepytime Rhyme board book focuses on diversity within families and the importance of love – not blood – binding families together into a “Heart Family.” Themes of healthy family attachments, family transitions, self-esteem, and acceptance are woven throughout this thoughtful and heart-warming story. The pairing of the Slumber Sloth and Sleepytime Rhyme is perfect for normalizing diverse family structures and empowering children to take a fluid and positive view of the important relationships that shape our lives. It emphasizes that whether near or far, we carry our families in our hearts.

For every Hartley Bundle purchased, Slumberkins will donate a portion of proceeds directly to the Alliance of Moms. When you choose to purchase this bundle, you are directly impacting the organization and the young mothers and fathers they support – empowering them to become informed parents who are equipped to give their children the healthy childhood they so deserve.

Our Hartley Bundle will be available on May 1st, 2018.

    I’ve been a foster mama for almost 15 Months to a beautiful baby girl. We said yes to bringing her home when we were 30 weeks along, and both girls are such sweet blessings to us. Both girls would love this sweet book.

  • Amanda

    I’m so excited about Hartley. I’m a new foster mom and a few other foster moms have recommended your slumberkins. I currently have a sweet foster baby. I would love to purchase Hartley for him and future fosters that we are privileged to love.

    This is so amazing! Some of my friends have adopted and it’s ai wonderful to watch their journey and love. I hope to adopt in the future when my girls are older❤️

  • Stephanie

    Love the collaboration you’re supporting specifically because my parents were foster parents for over ten years then went on to adopt 5 children who they fostered. I fell in love with a baby girl through foster care, hoping I’d adopt her one day. She was in my care from birth to 7 months. Later she was taken from me and adopted by a relative. I was heart broken and could not bring myself to foster again. Blended families, foster care and adoption is such a huge part of my life and I’m so excited that I can join the Slumberkins family with a new character that we can completely relate to! My kids and I can identify with being apart of a blended family so Hartley will be such a special addition to our home! We’re so excited for the release!
