“We’re thrilled, at this time of year especially, that we can raise awareness for Down’s syndrome and educate children on the differences that Down’s syndrome comes with, and what makes these kids special,” Rosie’s father Jason Kneen, from Faberstown, told the PA news agency.
“The nice thing about Lottie is that they’re very diverse and inclusive in terms of how they approach the design of the dolls.
“It’s really important that they have done different disabilities, different body types, and this is a great opportunity, with the extra information that has gone into the pack as well.”
The Rosie Boo doll features odd socks, a symbol worn to celebrate WDSD, and supportive boots to help with walking.
Mr Harkin said: “We have learnt how playing with toys with differences helps develop empathy in kids before culture determines how we should react to differences.
“To me, that’s one of the most powerful things we’ve discovered about doll play, the positive impact that can empower kids but also potentially to help reduce bullying by normalising differences.
“It’s incredibly powerful for kids to be able to see a doll in their likeness but equally it’s important that all kids have a diverse toy box.”
