what age accurate ang IQ assessment?

at the age of 2 yrs old and 4 months, my daughter can identify the alphabet and their sounds, numbers 1-40, shapes, and animals. she already read simple words like cvc, names of colors, and animals. she loves to sing, she can sing not only nursery rhymes but also Christmas songs, at kahit ibang kanta basta marinig niya ng 2-3 times kaya niya na kantahin. minsan nga napapacheck ako sa google kung tama yung lyrics e, tama yung lyrics na binibigkas kahit medyo bulol. may mga nagsasabi lang sa akin na ipaassess ko daw ang IQ. #firstmom
