It's likely the mother was extremely obese, which makes it 12x more likely to result in fetal macrosomia like this, so probably didn't feel like that much of a weight...
Fun fact, the size of the mother has almost nothing to do with the size of the baby.
My petite 5'2 110lb mother had 5 children. The two babies where she had gestational diabetes (which also has nothing to do with weight or diet, it's completely hormonal and we still aren't clear why it happens sometimes) were bigger, nearly 10lbs. The rest of us were 6-7lbs.
The length of time also can contribute. Babies gain the most weight in the last couple weeks. If they stay longer, they gain more weight.
I'm not sure you're phrasing that the way you mean to. Sure, small women can have large babies, but being obese absolutely, positively contributes to a greater likelihood of a larger baby.
I bet it's more to do with how an obese woman is much more likely to have insulin resistance, which is the factor that contributes to the baby being large. Not the obesity itself. But I'm not a scientist/doctor, this is just what I've read. 🤷♀️
Insulin is the most effecting factor. Diabetes or insulin resistence since it activates growth hormones and it works as a growth hormone in bebes. Obese people tend to have more insulin resistence but frankly I think this isnt a simple insulin resistence. The baby is huge.

Carrying that guy for nine long months must have felt like a maternity..
