LII. A CHILD THAT WOULD NOT TALK 



Margaret M. Nice 

 Norman, Oklahoma 



Our tiiird daughter presented a fascinating subject for study 

 l)ecause of her unwillingness to try to talk in conventional fashion 

 until after her third birthday. Our eldest daughter (3 and 4) 

 showed a somewhat precocious speech development, saying her first 

 word at 13 months, having 145 words at 18 months, 1139 at 3 years 

 and 1765 at 4 years. Our second daughter (5) started to talk late 

 — at 20 months — and had only 45 words at 2 j'ears, but she learned 

 rapidly from then on, having a vocabulary of 856 words at 3 years 

 and 1505 at 4 years. Our fourth daughter said her first word at 

 IS months; had 155 words at 2 years and 804 at 3 years. 



Our third child said her first two words — "er-er" meaning pig, 

 (an imitation of the grunt) and "mamma" when 16 months old; 

 these two words sufficed her for four months. At two years her 

 vocabulary consisting of 5 words, the two already mentioned, "hot," 

 "wawa" for dog, and "baba" which originally meant bunny, then 

 various .smal! animals and birds and at this age chiefly baby. Vocab-
