Rachel Accurso, widely known as Ms Rachel, has become a prominent figure in children’s educational media, amassing a substantial online following through her YouTube channel and related content. Seven years after uploading her first video—an original counting song aimed at preschoolers—Ms Rachel’s channel now boasts over 21 million subscribers. Since signing with Netflix in 2025, her series has been streamed more than 69 million times, establishing it as one of the most popular new children’s programs available on the platform.

Ms Rachel’s content focuses on early childhood learning, using songs and play to teach foundational skills such as first words, phonics, and potty training. Her videos have drawn comparisons to major pop culture productions, with one clip viewed over two billion times. The channel’s success has expanded beyond digital media, with branded merchandise including dolls, rattles, books, and clothing, as well as an album release scheduled for this month. The creator attributes much of the project’s success to a collaborative approach with her audience, tuning into the preferences and feedback of parents and young viewers.

Rachel Accurso, 43, is a former preschool music teacher with two master’s degrees in music education and early childhood education. Her professional background informs the scientifically grounded methods used in her programming, which emphasizes quality content in an industry often criticized for excessive screen time for young children. She co-produces the videos with her husband, Aron Accurso, a former Broadway music director, whose organizational skills complement her creative drive.

During the COVID-19 pandemic, when many parents sought new ways to educate and entertain children at home, Ms Rachel’s channel experienced significant growth. The pandemic era marked a turning point, accelerating the brand’s visibility and appeal.

Beyond her work in early childhood education, Rachel Accurso has become increasingly vocal about political and humanitarian issues. She has publicly criticized the Israeli government’s actions in Gaza and campaigned against family immigration detention in the United States as well as the conflict in Sudan. Additionally, she advocates for LGBTQ rights, supports proposals for slavery reparations and universal childcare, and has endorsed progressive political figures such as Zohran Mamdani, New York City’s left-wing mayor, and Abdul El-Sayed, Michigan’s Democratic Senate primary winner.

Her stance on these matters has sparked controversy, attracting criticism from conservative audiences, including accusations of antisemitism following her remarks about Gaza. Ms Rachel denies such claims, emphasizing her concern for children on all sides of conflicts and her collaboration with organizations like Parents Circle, which brings together Israeli and Palestinian families affected by violence. Despite facing backlash, including a nomination for "antisemite of the year" by the pro-Israel group Stop Antisemitism, Ms Rachel stands firm in her position and maintains she is motivated by a commitment to protect children’s rights on a global scale.

Some Jewish parents have reportedly shifted their support to another children’s content creator, Ms Sara, who focuses on Jewish cultural programming. Ms Rachel expresses respect for Ms Sara and does not discourage families from choosing alternative content.

Accurso has also taken a principled stand in her professional collaborations, refusing to associate with individuals or groups who have not publicly condemned violence against civilians in Gaza. She argues that privileged voices have a responsibility to speak out, suggesting that collective action could help end ongoing violence.

Raised in Maine by a single mother, Rachel describes her upbringing as challenging but rich in love and resilience. Her early experiences deeply influenced her values and informed her decision to pursue a career connecting with children, especially those facing hardship. She initially considered entering the ministry but was drawn to teaching after developing a strong rapport with disabled children.

Rachel met her husband Aron through a shared interest in music, and the couple married in 2016. Their combined expertise and personal chemistry have been central to the authenticity and success of the Ms Rachel brand.

Despite the complexities surrounding her political activism, Ms Rachel remains committed to using her platform to advocate for vulnerable children and marginalized communities. While she has no plans to enter electoral politics, she hopes to pursue a future path as a Christian minister. Until then, she continues to balance her roles as a content creator, advocate, and mother of two young children.
