Suggest Treatment For Accidental Consumption Of Cologne By Children

I am really worried for my son although he looks alright. After we took a bath he opened the bottle of baby cologne and accidentally drank it. I just turned my back for a second and hear him coughing then I saw the bottle was opened next to him. I gave him water, lots of it. It s been 30 minutes now after the incident and he s alright. He even ate his dinner and he ate a lot. What should I do about this? Will he be ok?
