We also already knew Belle was serving in Rumple's castle quite early in the timeline from The Evil Queen, when Rumple mentioned he had a a maid. The only assumption we can make is she served him for a good two years, since Roland is four when the Curse was cast, and it might take another couple of years (Snow's pregnancy + the time between Snow Falls/Drifts and her wedding) before we get there. Roland must be two years old by this time.
