What everyone else said Personally with DS1, who was a 35 weeker, we stopped mentioning it, even to HCPs by 12 months. With DS2, who was a 33 weeker, it is still a pertinent fact, so we still mention it. But I'm guessing by the time he's one it won't be a big deal anymore. DS1 met most of his milestones at average times, mostly his corrected age. DS2 seems to be doing the same thing. It's funny though, DS2 struggles to 'do' things (I'm assuming because of his prematurity and size), but is much more motivated than DS1 ever was, so he gets there anyway
