Aw, ang frustrating nyan mama, nakakaawa talaga! One of my mum friends had the same issue at 3 months, lumipad lang siya sa bottlefeeding kasi biglang ayaw ng baby, and she swears by trying teat feeding (yung parang latch sa breast ang nipple shape), plus warming the bottle under warm water bago i-offer so it feels more like breastfeeding, at sometimes kailangan mag-take a break muna for a week or two before trying again. May isa rin sa amin na successful when she pumped less at nag-direct breastfeed more para ma-reestablish ang latch preference ng baby, pero yan lang kung kaya mo physically. Honestly, at 3 months babies can be weird na with preferences, pero usually settles lang after a few weeks, so don't lose hope, you're doing great!
