Fussy baby at breast due to previous choking incident

Has anyone experienced a fussing baby at breast due to baby choking/coughing from a previous breastfeed? My 1.5 month old baby seems to remember a choking incident (although v light, with slight coughing). The choking is likely due to a fast letdown. My baby now fusses a lot/refuse to eat from that side of the breast which caused the choking. What are the ways you have continued to encourage baby to feed without fussing? Would using a nursing pillow help to reduce choking incidents?
