DDPsplit w/ out of pocket?

[odhrty]

Can I use DDP for self, husband, and 9 year old daughter, then purchase a kids meal for my 10 year old at one TS meal? I have to purchase an adult DDP for him but he will want to order from the kids menu most times. If I can do this then can i use his TS credits towards our signature TS meals? I'm not trying to take advantage of the system but don't want to be taken advantage of either when he's still eating chicken strips. Any advice? Thanks
