Memang biasa jugak at this age untuk baby kurang minum dan tidur lama, tapi dengan kombinasi tak membuang selama 2 hari, kencing macam kurang, dan baby cepat jadi tired during feeds, I think it's worth checking with your pediatrician atau lactation consultant tadi aje, bukan alarm, tapi better safe than sorry lah, especially since you're unsure kalau dia truly full after direct breastfeed. Bab supply you seem okay (1oz tumpah is good sign!), tapi sometimes baby yg baru adjust to direct breastfeeding boleh get frustrated or tired tengah cara, or ada tongue tie issues yang bikin dia susah extract susu even though it's flowing. Dalam meantime, after he does direct breastfeed, try pumping atau express sikit to check how much he's actually taking (kau boleh tahu dari volume tumpah ke botol), then supplement with that bottled milk if needed, tak payah rasa bersalah, kau dah usaha DBF hard enough! The fact dia willing to nurse now after months of trying is already win, jadi just make sure he's getting enough through whatever combination works. Good luck, mama!
