How many children do you have?

Today I got THE question again, 

the question I have panic attacks over when I have to answer

"How many children do you have?"

It's not that I don't know how many children I have or that I don't want people to know.

I know I have 3 sons 3 beautiful sons.

It's the look I get

you know the look of "Oh but I only see 2 boys here"

Some people ask me where my 3rd son is sometimes too.

Then I feel like I have to explain 

so I said "These are my 2 older sons my baby passed away from SIDS"

I don't know why I feel I have to explain really it's none of their business. 

But I feel like I have to let everyone who asks about my kids know about Carter. 

He's my baby I want them to know about my baby.

I just don't do well with the looks I get.
