The YouTube star Ms Rachel, toddler whisperer extraordinaire, spots me before I clock her, and even from a distance and without her trademark pink T-shirt and denim dungarees, she is instantly recognisable by her wave, which is accompanied by an enthusiastic bounce. I half expect her to say, “Hi, friends”, as she does at the start of many of her videos. Instead she bounds over, wearing a classic off-duty mum uniform – Sesame Street sweatshirt, grey leggings, baseball cap that reads “Mama” – and removes her oversized sunglasses. She’s very sorry, she says, rubbing her eyes, that she is so tired – but her manner remains unfailingly, characteristically peppy.
It is only seven years since Rachel Accurso, who used to be a preschool music teacher, uploaded her first video to YouTube, a counting song for preschoolers called Bubble, Bubble Pop!. She and her husband, Aron Accurso, who worked as a music director on Broadway, made the video because their one-year-old son had a speech delay and there seemed to be a dearth of quality videos online that could help toddlers learn to speak.
