Weird question, but were all your kids born in either warm weather months/cold weather months, or all in/around the same
All my moms kids were born in spring/summer. 1 in March, 2 in may, and 1 in August.
My sisters kids were born in April and may.
My SO's moms kids were all born in October or November.
My gmas kids were all born in may, July, and august.
