How to pump while working..

So, I’m probably gonna get hate for this anyway but it’s something I already discussed with my doctor the minute I found out I was pregnant & she was fine with it.

I work in a cigar lounge. *I DONT SMOKE* I’m currently 29 weeks pregnant with my second child & hope to breastfeed once he’s born.

The only thing is I don’t see how it’s going to work with my pumping because

1) Storage: we had a refrigerator but I’m concerned about the odd chance of me accidentally leaving things behind or just storing it in general.

2) I’m the only employee besides the owner & we work completely opposite schedules. So unless I shut down the whole store for 20 minutes every so often & hide in the bathroom to pump the store will be left unattended.

3) The smoke. People are allowed to smoke inside here, but it’s really well ventilated. I still worry about that affecting my breast milk though.

Is breastfeeding like totally out of the picture when I return to work after taking maternity leave?
