Bed times...

What time do you put your baby to sleep and how does he or she sleep during the night?

My son for the past couple days has been having a hard time falling asleep for naps and bedtime. I think he might be going through a sleep regression. I read online that an earlier bedtime and last nap over by 4pm should help him sleep more! He currently goes to bed at around 9. Is anyone else having this problem?

Thank you for your input!!
