If a woman has 3 births in this pattern:

January
That December 
The following November 

I know individually they’re Irish Twins, but does this pattern have a different term?

I assume that would just be Irish triplets - no? The 'Irish' basically just means that less than a year goes by between births.

That makes sense Bro.

Bro: went to Google. Yup,”Irish Triplets”
