The poor bubby! Coco had a temp too after teh needles. Went after about 24 hours. Bummer about the sleep!! Have you tried topping her up with EBM at night before her last feed to see if that helps. It really helped Coco, and the formula didn't.
anyway, gotta run, the damn gardener has started the leaf blower SO annoyed, Coco WAS asleep...
