Aww, ganyan talaga with bottle refusal, sobrang frustrating! Have you tried Tommee Tippee? A few of us sa mommy group namin, ang babies nila mas nag-latch sa softer feel ng Tommee Tippee teats compared sa Pigeon, kaya baka worth trying pa. Since syringe feeding naman ang ginagamit sa bahay, baka okay lang din i-continue yun habang kelangan, tapos slowly introduce the bottle, sometimes babies just take time to adjust, lalo na kung breastfeeding-preferring sila. What size teats are you using ba, stage 1 o 2 na? Sometimes timing and a different approach (like bottle at angle vs straight, o warm bottle) helps din, not just the nipple itself!
