AIC values for models containing combinations of the significant predictors from regression analyses in Study 1

Model	Model ID	AIC
Child Sex + 16-month MCDI Production	1	118.79
23-month MCDI Production	2	116.68
23-month CCT Comprehension	3	108.49
Child Sex + 16-month MCDI Production + 23-month MCDI Production	4	116.75
23-month MCDI Production + 23-month CCT Comprehension	5	105.48
Child Sex + 16-month MCDI Production + 23-month MCDI Production + 23-month CCT Comprehension	6	107.03

Note. Child Sex was included only in models that contain 16-month variables since it did not reach significance in the 23-month model.
