I’ve read accounts about the Vikings also having this practice. The father would examine the newborn child at birth and then decide its fate.
I don't think I've heard that & the first thing that I thought of when you mentioned it was Egil's bones & also Ivar the boneless, along with his brother Sigurd snake in the eye. Physical deformities were something of song & legend, so eliminating indivduals with them at birth would seem to be odd. I'm not saying they didn't or couldn't have, only that it doesn't fit with other things that are known about the Vikings.
