Breastfeeding helps contract the uterus. Your uterus should be about the size of a lime about 6 weeks after. The shape of your abs is another story and is entirely based on how much weight you gained, the size of your baby, how big your tummy was stretched, and the elasticity of your skin.
Making the world better, one answer at a time. The climate at the beginning of the Paleozoic era was moderate, but managed to stabilize during the mid-era. At the end of the era, the levels of oxygen in the atmosphere increased and carbon dioxide levels decreased.
In both cases, the answer is: huge variation. Throughout the 180 million years of the Mesozoic (the era that encompasses Triassic, Jurassic and Cretaceous), there were huge variations in average temperature, sea level, atmospheric oxygen, atmospheric CO2 and many other variables. There was no one âMesozoic climateâ. So at some times and places, humans would have been very comfortable (at least until they got eaten by theropods). Other times and places would have been uncomfortably hot, cold, dry, humid, inundated or otherwise unappealing.
