"I am giving my son the turtle."
Translation:Jeg gir sønnen min skilpadda.
If you put the possessive pronoun ("min") first, you have to use the indistinct (sorry I don't know the correct grammatical term) form of the noun: "Jeg gir min søn skilpadda." If you use the distinct form, "min" has to be behind the noun: "Jeg gir sønnen min skilpadda." Hope that helps...
