I found this recent article on Google:

But I would also suggest that you take some fish oil or Krill oil supplements, and/or eat more salmon or Omega-3 enriched foods (like Smart Balance products).

When women have children, this places a huge load on the mother to provide the essential fats for the baby's brain and nervous system development. Often then, the mother becomes deficient. So taking these and/or eating the right foods can replenish you.

The article suggests that this is neurological and genetic. But it could be you just need some replacements after childbirth.

People who expose their bare hands to cleaners/detergents alot, or solvents (like paint thinner or mineral spirits) can defat the skin of oils, and the fingers will prune up as well.
