The dear doctor, whether it is possible to tell or say unequivocally, that the child lags behind in development if to the girl of 7 months, and she does not creep yet and to not have a seat itself though already costs or stands on legs or pinches.
Whether the child at this age articulately should say syllables? At malyshki it resembles any low more. It is normal or not? In advance thanks for the answer
