We have 2 kindle fires for each of our kids: 7 YO and 10 YO. Like most kids all they want to do is watch YouTube. I'd like to let them do that but with time limits and blocking inappropriate content (I know the blocking isn't perfect). It seems like if I enable free time, there's no possibility for accessing YouTube.
Freetime also seems to have weird ideas of what websites are appropriate for a 10 year old child. I tried setting the age range in Free Time to the range 10-13+ and it's still recommending "Paw Patrol" and "Nick Jr. Preschooler." This is for a 10 year old whose read the whole Harry Potter series and reads a 300 page young adult novel every week.
Other than me having to set a stopwatch or something is there an easy way to set time limits on a Fire without using Freetime. The Windows parental controls, which I also use, seem to work a lot better.
