My son is a month old and mostly EBF. (I pump and let him nurse on demand, comfort nurse and nurse to sleep)

I start back to work on the 28th and have no idea how to start going about helping him adjust early to me being back at work. I work evenings from 4:30

-5:30 to between 8-11:30 (depending on the day)

He hates pacifiers and lately he rejects formula (we've had to supplement in the past)

Does anyone have any experience with this?

If so, what did you do?

We tried a small test run tonight that went HORRIBLY!!!! Help!! TIA
