My 2.5 year old wakes up way too early at 6 am. I get her to bed at 7.30pm. Is that too early a bedtime?

Kids at this age usually sleep for 12 hours at night. So this waking time seems about right if she goes to sleep at 7 30am. I guess in Singapore, most children sleep after 8pm. I think at this age she should be only taking one nap in the afternoon. My advice would be to let her sleep at 8pm and I think the situation will improve. You can also try to wake up 10minutes before 6am to start patting her so that she doesn't wake.
