I think DA meant the large age gap between the kids...but the family portrait indicates that there's only a few years between them really. 4-5 between Weiss and Winter, and maybe 3-4 between Weiss and Whitley. That's a 7-9 year age gap between Winter and Whitley, which isn't overall that big when you have another child in the middle. It's spaced out, but that just means they finished potty training/teaching the previous one to walk and talk before they had the next.

Large age gaps are generally considered large if they occur between the children that were born next to each other like Weiss and Whitley.

For all we know Willow and Jacques just had trouble conceiving/carrying children to term. It happens.
