First, raising children shouldn't be an onerous business for two or just one; the current monogamous family is a construct from a few religions with outsize cultural influence (Paradoxically, in the absence of contraceptives monogamous families are good for population growth: you use the bare minimum of adults to raise more than a dozen kids. Ideal stuff if your goal is to go to war with the tribe on the other side of the Nile). Second... well, second we should forsake heaven, and remain here. Let's keep working on life-extension and rejuvenation, and abolish death.
