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.
The Paleozoic Era, which ran from about 542 million years ago to 251 million years ago, was a time of great change on Earth. The era began with the breakup of one supercontinent and the formation of another. Plants became widespread. And the first vertebrate animals colonized land.his was the time when plants evolved, though they most likely did not yet have leaves or the vascular tissue that allows modern plants to siphon up water and nutrients. Those developments would appear in the Devonian Period, the next geological period of the Paleozoic. Ferns appeared, as did the first trees.
