Aih, malam bangun minum susu memang common lah masa ni, especially kalau solid dia tak consistent, a few of my mum friends pun sama situation. Adik dia mungkin comfort sucking more than actual hungry, tapi kalau solid intake memang kurang, boleh try introduce more calorie-dense foods macam avocado, nut butter, or yolk yang dia boleh main-main mkn during the day, so nighttime dia puas sikit. Pastu boleh gradually reduce night feeds, tapi jangan tiba-tiba, buat dia stressed. The good news is combined breastfeeding + formula means dia still getting nutrients, so try relax on the worry, at 2 years old, solid food yang dia willing to makan pun dah counted lah. Consistency over perfection, mama!
