Bath time

I feel absolutely horrible. I accidentally poured a cup of water in my 2 months old ear during bath time. I tried to rinse out the soap in his hair while I was taking a video of him & I totally missed his head and into his ear 😭 he was fine until I took him out & he started screaming Bloody Mary, now he’s fast asleep 🙄 should I be worried? He usually screams for a little afterwards cause he’s cold, but I immediately put clothes on him & he still wouldn’t stop. I think it’s his ear..
