Ahhh I feel your exhaustion, mama, 2 minggu of broken sleep is really tough! At 5 months, banyak possibilities lah, bisa teething early, sleep regression, atau dia just going through a phase where dia tak nyaman during that time. A few of my mum friends ada baby yang jaga tengah malam gila-gila, ternyata reflux atau gas yang tak kita perasan, so worth checking with your doctor first to rule out any discomfort, terutama since it's been consistent for 2 weeks. In the meantime, try rotating your soothing methods (jangan semua on at once, kadang dia overwhelmed) and maybe track if ada pattern, macam dia hungry at that time ke or uncomfortable after feeds. Hang in there, ini phase nanti pass, but definitely get a professional opinion soon so you can rest better knowing he's okay.
