My child gave my 10 month old melatonin!?!

I took a quick shower while baby was in bouncer and my 5 year old got I to the melatonin gummies and gave baby one!! He only ate half of it and they’re 1 mg a gummy. I’m feeling really paranoid. Will he be okay? Or do I need to take him to the doctor!? He fell asleep shortly after eating it. I’m sure he only ate this amount because we only had 3 gummies left and there was 2 left in pack.
