Agak normal lah di usia tu, sebab mereka tengah dalam periode developmental leap jadi otak depa memang hyperactive sikit, tapi kalau dia really restless dan payah tidur sangat, better check dengan pediatrician sebab kadang ada reflux atau sensitivity yang bikin baby susah settle. A few of us dalam mum group had babies like that, and turned out ade reflux issues yang once treated, tidur jadi better. In the meantime, try darkening the room, white noise, atau swaddling, membantu some babies. Jangan stress sangat, normal phase aje tapi memang worth checking with the doc just in case!
