Aiyoh jangan risau sangat, actually banyak babies yang berjalan lambat and it's totally normal! A few of my mum friends punya anak, one didn't walk until 15-16 months, another one 18 months, and semua fine je now, berlari-lari suka hati Since your little one is just over a year, boleh tunggu lagi a few months, tapi if you're really worried, might be good idea to bring up with the paediatrician just for peace of mind, they can check if everything is progressing okay.
