Early wake up

Dalila

Hi ladies! So my son was good about waking up around 6:30, worked perfectly for us. Yet, all of a sudden he’s waking up at 5:45 and will not go back to sleep!! It’s been a week with this.

Bedtime is exactly the same, not sure what’s happening. Could light creeping through the window cause this?! We don’t have blackout curtains, so light slows my does come in. This is the only thing I can think of.

Any ideas how to make early wake ups stop?
