Aiyoh, I haven't tried Buai Mesra Travel specifically, but a few of my mum friends yang travel dengan babies swear by those portable baby swings, convenient saja when the baby gets fussy kat hotel or rumah relatives. The thing is, it depends on your baby lah, some babies suka tengok motion, some just want to be held je! If you're thinking of buying, maybe check the reviews carefully dulu to see if it folds up small enough for your travel bag, sebab that's usually the hassle kalau travel dengan little ones.
