The first Joint Play in Partnership Conference at the Queen's Hall in Narberth attracted over 100 representatives from Pembrokeshire and Carmarthenshire.
They included those who work in the voluntary sector and the statutory sector as well as playworkers and club staff from many types of organisations in both counties.
Presentations were given by Pantyfynnon Communities First, Llwnhendy Integrated Children's Centre, Pembrokeshire Open Access Play Action Team, Carmarthenshire's Early Years service manager, Pembrokeshire's 0-10 programmes manager and Tim Moss, regional development co-ordinator.
Keith Towler, Children's Commissioner for Wales, was the keynote speaker.
The event helped to promote play and the importance of play for children and young people as part of lives.
Meanwhile, feedback from the conference has been extremely positive, with over 40 people expressing an interest in becoming part of the Play Association which will be developed in the near future in order to drive play forward in both regions.
Said Mr. Towler: "These conferences provide practitioners with an ideal platform to share ideas and good practice and it was great that I could play a small part in that.
"Play is such an essential part of a good childhood. It provides children with solid foundations that will stand them in good stead for the future and it helps build children's social skills and confidence and improves their overall well-being.
"I sincerely hope that the work I've seen with children and young people in Carmarthenshire and Pembrokeshire will continue and that practitioners will carry on sharing information in this way."
