Sam was born at 36 weeks. I've been told that I can expect it to take until he's two before he has fully caught up developmentally.

As for constantly going by his corrected age - ie, him being 6 months corrected when his actual age is 7 months - I think we stopped doing that ourselves at around 8-9 months. The medical world stopped at about 12 months, but still note that he was born prematurely for some things.

Honestly, it all depends on the baby. Despite being premature, Sam has done some things quite early, even for his actual age. He's also doing some things quite late and is big for his age, so nobody would really be aware that he was a prem at 21 months unless they were told.
