Suggest Remedy For Seizure

I think my granddaughter had a seizure and when we took her to the er we were released and told to observe her because she didn t have any sign currently. She is 1-1/2 and was in daycare. It scared the heck out of her teacher and they described my granddaughter has walking sortta in a drunken state, her left arm drawn up to her chest and shaking, she said she was non responsive but had a look of horror and then she fell and hit her head on the table. We rushed her to the er and after waiting 3-1/2 hours, went into the room and they briefly examined her (no blood work, x-rays or nothing) just listened to her lungs, looked in her ears and checked to see if she was running a fever. They said she appeared to be fine and to take her home but observe her ever 2 hours.
