To prevent weight gain on birth control, don't change how much you eat or exercise. If you were gaining weight before starting birth control, you'll probably continue to gain weight after starting birth control.
Birth weight around 600 grams

Adult Wolf Spiders are about as big as your middle finger and your thumb curved to make a ring. I have wolf spiders in my home and i have a phobia of spiders, especially the big spiders. they are as tall as about an inch, or maybe half an inch. The "not fully grown" spiders are much faster than adult wolf spiders. These kinds of spiders are harmless, as well as 97.8% of all spiders in America.
About 12 pounds immediately after parturition.
Spiders do not give birth. They lay eggs. Typically they lay their eggs in a silken sac of some kind that is sealed until the spiders start to hatch. The silken sac is carried around by some spiders such as the wolf spiders, or may be hung in or near to the spider's web. Different spiders have different places to keep their egg sacs safe.
Usually around 2 oz.
Immediately after birth, it is the weight of the baby plus about 5 or 6 lbs, to account for the blood loss and placenta delivery. More weight will be lost as you lose more blood from delivery and if you breast feed you will lose weight faster.
