We just incorporate all the excuses into our bedtime routine. supper, bath, brush teeth, bed. Nothing to eat or drink after teeth brushed except water. Then we go potty, get drink of water, & sleep. We told our kids that they were not to wake us unless they saw sun coming through the windows. I then told them if they wake early then they can play quietly in their rooms only! So far no problems here. now 4 & 5 both are potty trained & get up & go by themselves & get back to bed without bugging anyone else. For nap time, I changed to quiet time. told them they were big kids now in the big bed so they didn't have to sleep, but now have quiet time. they have to stay in room 1 hour & play quietly. I set timer. My son would fall asleep, daughter not, but both stayed in room. I would just tell son he must be going through a growth spurt. :) My daughter will nap every now & again & this is her excuse too. Hope this helps you.
