I can't imagine anyone wanting to have to deal with raising a toddler in their 60s and a teenager in their 70s. Sure, people do it (e.g., grandparents adopting their grandchildren for whatever reason), but this seems like a generally bad idea. Better would be to just make things easier for parents. Cheap or free childcare, for one thing.
