Wet suit for small child (Wormbridge HR2)

My daughter lives in Norway and has a young stepchild. They live next to a river and occasionally (like today) it’s been warm enough to paddle in there. The child also decided to lie down (she’s 4). Following this she became very cold. The weather and the number of times they can go in the river makes buying a new wetsuit ridiculous. The little girl is very petite but will grow, so I’m wondering if anyone will have a wetsuit available at the end of the season please, for me to take out in January. Aged 4-5 would auit for next summer.
