Asking for 5 Min and 10 Mins delay for bathing and brush ..

Hi,

I see my kid who is 5 + , always ask give me 10 mins more sleep, when I ask hime to getup, and come with me for brush & bath, even 10 mins given then he keeps on demanding 10 more mins, and its difficult to catch the bus.Although he enjoys bath, but doing brush probably an issue.. Many of times i need to force ( Like speaking loud, and telling few things like I will not do this or that with you ( Reducing his luxury what ever he enjoys :-) ) , this works but he feels frustrated and don't enjoy the activity and cooperation is reduced , hence become a tedious job in the morning.. I belive there should be better way , and hoping will get good practical answers ...

Thanks
