Sabar ye mama, 400g naik dalam sebulan tu actually okay pa untuk baby 2 bulan, growth memang jadi slower selepas bulan pertama, tapi memang sebaiknya confirm dengan paed dulu sebab dia boleh check latch, feeding pattern, dan overall health anak. A few of my mum friends also worried gila about weight gain time tu, tapi rupanya latch mereka yang perlu betulkan dengan lactation consultant, so susu pun jadi lebih efficient masuk tu. If paed say it's okay, jangan pressure sangat; kena ensure baby feeding regularly (at least 8-12 times sehari for mixed feeding), dan nampak dia wet nappies, pup normal, active ja, semua signs bagus. Tukar susu lagi-lagi bukan usually the answer cepat ssangat unless doctor advise; most mums improve by fixing feeding technique dulu. Kuat semangat, this newborn phase memang challenging!
