I have a wonderful 3 year old DS who has just recently developed a tic. (2.5 weeks ago). We have been to the dr, had blood tests to rule everything out, and now just still need to go to an eye dr to make sure his eyes are healthy. He has been blinking/twitching his eyes, sometimes tight, as well as grimacing and now most new, flapping his ear. I have done extensive research on transient tics and it appears as though they are quite common. I know that it is not stress/anxiety related. I am a stay at home AP mama and he is as fun and secure as can be. Never had any bouts of anxiety and we very rarely let our children see us stressed. I do have a new 8 mo DD, but he has adored.her from the moment she came to us with no jealousy whatsoever. My DS is extrememly bright and spritied:)...meaning he can be quite a bit to handle b/c of his bubbly personality. I have heard that it can be due to brain growth spurts, but is there anyone out there who has experience with this? How long did it last? What did they do to help? Any help/suggestions is greatly appreciated! I am so worried. Thank you so much!
