That's really silly to wait until a year! I don't understand why doctors are so weird about it. I EPed for DS1 for 17 months because the ENT we saw wouldn't do it. We were referred to a different ENT at a year because he still couldn't move his tongue out of his mouth and he wasn't babbling. DS2 was tongue tied too and his was clipped at 4 days. DS1's frenulum has stretched out on it's own finally. It is such an easy procedure for a newborn it is surgery under general anesthesia if it's done at a year.
