My Mothers Boy Friend Dropped A Bottle Of Night Tylnoal

My mothers boy friend dropped a bottle of night tylnoal on the ground. We thought we got them all picked up, But my daughter went in their room to get the nail polish like she always does and I found her standing with one in her hand. I'm trying to keep her awake, because I'm afraid she took one. I need help! What do I do?! I've gave her milk, I put her in the tub because this hour of the day is her nap time. So this makes it worse because I'm not sure if she got her hands on another one.
