Absolutely, that’s a big one. I remember when the kids wouldn’t sleep through the night I would randomly grab four or five donuts in the morning and I could completely override any thoughts that it was a bad idea.

I guess for me, improving sleep involved lots of small changes:

Consistent bed time.

More exercise and sun exposure during the day.

Black out blinds at night.

The kids started sleeping in more so I can wake up naturally.

Cutting back on caffeine.
