well done

its such a big step moving them to their own room.... and if it helps i still check on my oldest girls several times a night!!! and they are 2.5 and almost 4!
and i moved my first daughter into her own room at 14 months only because i was expecting my second! but moved number 2 into her own room at 5 months because she was such a light sleeper, it would just take a sneeze or a cough or something to wake her up.
hope that it keeps going good and you start to sleep a bit better.
