4 month old sleeping scheudle

Rossi

My son's sleep is all messed up! He was going to bed at 8 and waking at 7. But then I read at 4 months you should trade the last nap for bedtime. So now he's going to bed at 6:30 but waking up at 5:30. So today I didn't wrestle him back to sleep I just let him be up. So now his first nap was at 7. Please share your sleep schedules with me! He will start daycare soon and I have no idea how that will look.
