The same way you have Emma, regina, Snow, etc in flashback. You cast someone else to portray the younger version.

Now, casting a younger Henry would be really tricky for the 7-9 year old version since he was 10 when he came to Boston to find Emma in the pilot. But you could probably find a child actor to handle that. Younger than 7 is a little easier (imo), since children tend to change a lot. you wouldn't have to be exact, but just close.

And, with the exception of Baelfire and Neal, I think the casting department has done an amazing job with finding young actors that would believably pass as the child version of the Older actor. So I am confident that they could find someone if the story required it.
