@reenalamba Just because he looks fine does not mean that he actually is fine. Hopefully you've taken him to a doctor or someone who can actually examine him or called whatever the local emergency number is for the country you're in (911 in the US, 112 in many other countries).
ETA: I really hope this is a spam account, because it makes me feel really bad that anyone in the care of a child would need to post on the Internet to get information on which emergency number to call in the event of a child overdose. Please learn these things if you don't already know them. They can save lives. Here's a helpful resource for after you've taken your nephew to be examined by a medical professional, for future reference: https://kidshealth.org/en/parents/help.html . Also, a general guide for emergency situations in which poison or overdose is suspected: https://www.healthychildren.org/English/safety-prevention/all-around/Pages/What-to-do-in-a-Poisoning-Emergency.aspx
