delay speech

Hi mommies, Mcm mana nk meransang anak untuk bcakap? Skarang my baby dlm 21 months. Suh panggil mak ayah xnk ekot..tapi kalau berlagu, ok je nk ikut ?..i mean, xclear, but we know it's her jam.. Btw, i live alone with my husband..xde family lain..and day time, my baby sent kt rmh pengasuh .bkn taska. Harap ade yg membantu. Thanks.
