2 year old threw phone...vent help!!

My best friends 2 year old son was sitting next to my 2 MONTH old son in the car playing with my friends phone then suddenly threw the phone at my innocent 2 month old babys FACE who started crying and sticking his hands in his mouth trying to soothe himself... What would you do? I demanded to be taken back home so i could take my son outa his carseat and love on him.. He seems fine. No bumps or marks but REALLY?! I slapped the toddlers hand and kinda yelled at him... He was being a brat, hitting my sons carseat then threw the phone at his little face. Wtf! I made my son stay up for like 4 hours before going to sleep cause im paranoid that it hit his head... 1st..do you think my bubs is okay?! He ate and took a bath n seems fine.. 2nd what would you do?!

This happened 7 hours ago and im still pissed....

I cant believe everyone is butt hurt over me smacking his hand 🙈 his mother told me too first of all and second of all ITS A PAT ON THE HAND!
