How would i sleep train?

Yes we want too.

We’re going to do cry it out no checks.

My son does not have a routine or bedtime because we’ve been traveling for 2months.

He does not sleep through the night at all 3-4 wake ups.

Do i just feed him in the dark in his room and lay him down almost asleep and walk out?

Update - cool but like i said we’re doing cry it out no checks
