Aiyah, jangan stress sangat, mama, slow growth doesn't always mean something's wrong, tapi you should definitely mention this to your OB/GYN at your next checkup so they can do a proper scan and check placenta function, okay? Sometimes baby just grow in their own time, especially if you and your partner pun naturally smaller build. You're already doing the right things dengan minum susu and eating well, that's what matters lah. Keep monitoring, keep your appointments, and try not to worry yourself too much sebab stress pun tak bagus for baby either. You're being such a caring mama by paying attention macam ni, and your doctor will guide you from here. Hang in there!
