babies plays like this...they can't move their body and move whatever they can...my girl almost turned from my mother's lap to my husband's at 2nd month...he was singing for her and she went excited...at 7month today she hold objects then stand and starts jumping, loses balance and fall...kids do it what to do...let them bloom their way... cherish these moments👼

he is jus happy or about to get hungry...... keep mittons on hand so that he wont scratch his face....

movement of hands is so aggressive that he scratches his face..
