Swansea Children's Centre is to offer yoga classes to babies as young as six months from later this year.
The service is currently only available for two- to three-year-olds who attend the nursery and involves three staff, who were trained in yoga through the centre's existing training budget.
All three staff members, whose training cost £200 each, are set to take an additional course focusing on babies. When this is completed the centre will open up the service as a regular drop-in session.
"We thought this would be a good way to improve the health and wellbeing of children. It also helps the children to wind down after playing," said the centre's development manager Cari Beuse.
The centre is open to families across Swansea but with a focus on the Blaenymaes, Gendros, Penlan and Portmead areas.
