A thousand tiny babies are taking to the water in Dublin this week to help sick babies in their own age group.
The infants -- some as young as eight weeks old -- are swimming through hoops and underwater.
Their aim is to raise €37,000 to buy a specialist incubator for the Children's Hospital in Temple Street which can provide live-saving intensive care for newborns.
The young swimmers are all members of Water Babies which runs more than 100 swimming classes a week for babies and toddlers starting from six weeks of age.
Babies of between eight weeks and 10 months will do a solo swim underwater and the intermediate group will swim through a hoop. Other babies will swim on their mother's or carer's back underwater or glide with them through a hoop, while toddlers will complete a training circuit in the pool.
Aisling Andrews, of Temple Street, said: "Babies in an incubator who need other treatment often have to be moved to a bed-warmer but equipment eliminates the need to transfer critically ill babies."
The hospital approached Water Babies two years ago with a fundraising idea. "We had set a goal of €3,000 but they raised €22,000 for vital equipment. This year we decided to ask them if they would like to raise money for their own piece of equipment which will have a Water Babies plaque," added Aisling.
Water Babies was set up in Ireland by sisters Carol and Therese McNally in 2002 and teaches babies to swim without flotation aids.
