Work and Breastfeeding

Hi Mummies... My LO is coming 5 mths and im planning to go back to work. My initial plan was to bf her till at least 6mths but finances doesnt quite allow that. However, i don’t wane stop bf-ing her. She will probably be away from me from morning 6am till noon 2pm. Im unable to pump at work too. Could fellow mummies share some tips on how I can continue breastfeeding when going back to work? Thanks in advance!
