Aduh, sama je situation dengan anak saya dulu! Biasanya anak yang reverse cycle ni kena gradual adjust, cuba consistency lang, every night dim the lights, buat routine yang sama (bath, story, cuddle), and resist the urge to play dengan dia malam tu even kalau dia hyper. One of my mum friends swear by putting baby in direct sunlight siang hari (helps reset their body clock) and keeping malam tu very dark and quiet, took maybe 2-3 weeks but berhasil. Lagi best kalau boleh check with your doctor juga, in case ada reflux atau other discomfort yang buat dia tak comfortable tidur malam, sometimes it's not just habit je. Hang in there, mummy, ini phase saja!
