You could try modeling wanting something but understanding that you can't get it right now if you don't already do that. Find something you want but can't buy and talk about how much you like it and why and how you wish you could get it but you can't right now. Then maybe talk about things you could do to get it in the future.
yes this I do. we look at all the stuff I want but can't buy right now, and we talk about how maybe I can ask for it for my bday or something like that.
