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.
Animal Life. The beginning of the Paleozoic era is marked by a sudden explosion of invertebrate animals, over 900 recorded species in the Cambrian period. It was only a few million years later that vertebrates appeared during the Ordovician period. The Devonian period showed an uprising in fish and other marine life. By the end of the Paleozoic era evolution had caused complex land and marine animals to exist.
