My daughter is the same way. She goes to bed usually at 7pm-- which stinks b/c Mon, Wed, Fri we don't usually get home until about 6:15. Tue/Thurs I pick up my kids at 4, so it's not as bad.
I have two suggestions. First, really work with your daycare. Mine has a set nap time 12:30-2:30 for the older kids, toddlers included. My daughter also did not want to miss out...but slept better on a cot in the toddler room, b/c everyone else was sleeping. Hopefully, he will transition into at least one nap a day and not be sooo tired at home.
Second, if he is that tired when you get home, let him sleep. At 9 mos, sleep is more important than eating dinner. My daughter used to do this. Most times she would sleep about an hour and then get up, eat and play for a bit.
Good luck...
