Lactation consultant

So I am breastfeeding and bottle feeding (with breastmilk) so the lactation consultant called to check in and she told me that once my baby gets back to her birth weight that she wants me to stop pumping and solely breast feed her. I told her what she wanted to hear to get off the phone but I'm like bitch are u serious! This is my daughter and this is what works for her. Not to mention that I have to go back to work in 6 weeks, what am I suppose to do go home on my lunch and breastfeed her? I just think that's out of control and really none of their business anymore, we're not in the hospital anymore. I just think that's ridiculous that your gonna sit there and be like I don't want u to pump anymore.
