I married Celia too.
I'm only on the second year of the boy version, mm my kids so cute. Now, I'm buying him all the toys, showing him everything, and introducing him to everyone. Theres nothing I really want him to be...so I'll let him choose.
There are 6 career choices. Your son's carrer can either be an Athlete, Animals, Music, Artist, Scholar, and Plants.
Plants would be the farming one...
To influence your son into farming, if you married Celia, give her flowers ever day...and show him flowers, crops, and seeds constantly, and befriend Celia(if not married to her)Vesta, and Marlin...and introduce him to them...and maybe show him their farm.
=D
I hope I helped...^_^''
