Female sloths give birth to one baby a year after a gestation period of six months. The baby sticks with the mother for about six months, grasping its momâs belly as she moves through the trees. This is an important bonding period that helps the offspring learn and develop.
Reproduction in Echidna. A female echidna possesses a pouch in the body where she lays an egg and it takes almost 10 days for the egg to hatch. After hatching, a very small sized baby echidna comes out of the egg. The baby is so small that it needs to spend three more months with mother in the pouch, and it is one of the prominent egg laying mammals facts. Their mother feeds them with the breast milk. Since female echidna does not have nipples, it is a little problematic for the baby to suck milk.
