A supposed to be a happy family day ends with an accident

No matter how tried we are to be safe in our daily living but accident is unpredictable.

Yesterday,we celebrated the graduation of my husband 's nephew.He graduated last Friday and yesterday we prepared a celebration for it.

My brother in-law ,his father decided to celebrate it in the beach so the kids will enjoy as he knows that kids loves swimming.

When we arrived at the beach ,the kids are so excited and enjoyed swimming.After I set the table ,I enjoyed watching them so happily .
I was not expecting that an accident will happen.

I even joined them so I can watch them all the time.

But then he saw his friend ,one of our relatives not wearing a shirt,so he was asking me to take off his upper rush guard suit.
I declined but he keeps asking me and tried to take it off in his own ,so I take it off.

He enjoyed swimming and a few minutes ,he ran to me told me that an ant bite him ,he was crying and shaking.I can feel that it's really painful.

I tried to calm him down ,I tried to calm my self .I get a vinegar and wash the affected area on his body .
I was so scared when I saw that his tummy slowly swollen.
I keep putting a venigar and I applied an ice on it.

It takes a minute when he stopped crying.

I feels so scared thinking about it as many cases like this that ends a human life.

I keep praying to God while doing anything I can do to make my son feel better.

Good thing that it's not the jelly fish type that it's really a poisonous.

I feel upset to the beach staff as they didn't warning us about the jelly fish presence in their beach.
If only I knew that there's a jelly fish in the said beach ,I will not allow my kids to swim there.

And since it already happened,I can't do anything about it.I was upset but I was thinking that it's an accident.
I even blamed my self that I take his shirt off.If only he didn't take off his shirt he will not suffered to much pain.

Thanks God that my son is okay ,he doesn't feel nay pain now ,he doesn't have fever,only he feels a little itchy but I applied an anti bacterial cream on it.

This happened to my son gives me a lesson ,a lesson that we need to be more careful and ask about the area.

And that it for today,anyway for those who knows about it what I should I do for the affected area coz he now he feels itchy?
