I returned to work 3 weeks after DD was born, but unfortunately it didn't work out. This was mostly due to the job (I'd only been there a short time and wasn't happy anyway), but I did miss DD heaps. I would arrange for DH to bring her in for lunch some days. I lasted about 4 months before my contract was "not renewed" (mutual decision by me and the employer).

If you can, see if you can get your baby brought to you at lunchtime so that you can feed them. Is your job flexible at all, e.g. can you work a morning or an afternoon from home sometimes? Do as much research as you can as to what you're entitled to. GL.
