Haiii! Alah anak 2y7m sudah boleh start lah, tapi memang bukan race kan hehe. A few of us tried tunggu dia show signs dulu, like nak masuk toilet sama-sama kita, or tahu when he/she nak pee, baru mulai introduce potty chair, jangan force sangat. Since you're working, maybe weekends boleh practice more relaxed, and then slowly-slowly he'll get it, some kids ambil 3-4 bulan, ada yang lama sikit, tapi InshaAllah semua anak boleh finally potty train!
