Formula - need help

Hi all,

My baby is combo fed and she has recently started hating formula. I tried today to combine it with expressed bm but she wouldn’t take it only ebm. I usually give her 3 bottles formula and the rest is ebm. I live in the U.K. so my formula options are slightly different from other countries. She has severe reflux and hipp organic worked very well with her sensitive stomach but if she wouldn’t take it I don’t know what else I can do? Any formula recommendations that are good for reflux babies and close to bm taste?
