Alah, buku 'Main & Cakap' ni memang bagus la, tapi honestly anak 2 tahun tu dah follow semua milestone yang you list out, so dia sudah on track! A few of us dalam parent group tried activities dari buku tu dan membantu sikit lang untuk buat playtime lebih purposeful, tapi the milestones you described tu dah menunjuk your child is doing great. Mostly buku tu useful kalau ada delay, but from what you shared, just terus engage dia dengan simple conversations, balas apabila dia point things, dan let him play alongside other kids, that's already what matters at this age
