Bedtime for 1 yr olds

Any opinions out there about what would be an appropriate bedtime for a 1 yr old?
I made a suggestion to a parent that the child was lacking sleep, after I learned the child was going to bed about 3 hrs later than I imagined. My suggestion was 730-8pm as a suitable time. What do you think? I would expect a child that age to sleep at least 10-12hrs a night, and maybe another 2 hr nap during the day. Am I off base here? This child is sleeping less than I do at night, which might explain the moods and crankiness. I think the parents thought I was nuts, and took offence to my suggestion. Thoughts?????

A couple guidelines that you may want to send to the parents depending on your relationship with them. Of course every child will be different though!

I used to put mine down at 6:30 but I didn't work , parents like to have some time with their child (at least some do !) I feel for them !! I would prob put mine to bed later too if I worked ! My six yr old is in bed at 7 and we read until 7:30 , she will sleep until 7:30-8 the next day .

My 2.5 year old goes to bed between 730 and 8 and sleeps until 730. Her nap is 1.5 - 2 hours each day. I couldn't imagine putting her to bed any later. She gets so moody if she doesn't sleep that long.
