Karen, I don’t know if you read my post, but we have chickens and dogs that require attention early. My children always get up no later than 7 or 7:30 and get in bed by 8:30. My son is the main chicken-farmer; he makes sure that they have water and food prior to going to bed, that way he doesn’t have to get up earlier than 6:30 or 7pm.
I would say that she is old enough to be getting up early due to assisting the family on the homestead. My opinion is that it will make her a good citizen as an adult and productive throughout the day – she will develop a very good work ethic as a result, too.
Put her to bed early and give her an alarm; her body will adjust. She may need a nap later in the day – especially during the transition period – but not too late so it doesn’t interfere w/bedtime.
I must admit, I’m a little perplexed by what seems like a view that if a child wakes up early, then they aren’t getting the sleep that they need. I would agree if the child is allowed to stay up late then that’d be the case, but not if the child goes to bed at a reasonable hour.
Also, remember, in their future, they will have days that they stay up late for whatever reason. They have to be able to get themselves up, never-the-less for obligations such as college, job, family, etc.
I think that sleeping late should be the exception to the rule and be considered a treat (or during sickness, the standard is different).
When my children have growth spurts, they don’t sleep in later, they go to bed earlier.
