Hello! My near 8 month old has begun a very odd thing he balls his hands up into tiny little fists, goes completely stiff and near purple in the face like he is having a mini temper tantrum. I am just wondering has anyone else seen this? He usually does it in his highchair when he's being fed if you take a 2 second break he seems to get angry or he just does it randomly in his chair or at my parents house he has been known to give it a go too. Besides this he is a very happy little man and very smiley and giggly. My husband and I were just wondering if anyone else has experienced the little fists and angry face before?
