Following the development of a baby’s renal system, he or she will start to release urine. He or she will then drink it, and then pee it out again. A cycle which will repeat until delivery.

An unborn baby’s fingerprints will begin to form between 6 to 14 weeks, though they will not be fully formed until around 6 months. There are factors in the womb that will contribute to how these unique patterns appear, which include the location of the foetus and the amount of movement he or she performs while in the womb.

A four-month-old baby should recognize toys, particularly ones that rattle, make fun noises, or are bright in color. They may reach for toys, shake toys, or swing at dangling toys.

At four months, a baby’s leg muscles are beginning to form. When his or her feet connect with the ground, and their bodies are being supported, a four month old should push back against the floor, straightening his or her legs out.

At six months, a baby would be able to recognize and show preference to their family members. A six-month-old baby should begin to notice strangers, and be apprehensive of their presence. They may be genuinely affected by shows of emotion. They should also be interested in snuggling, cuddling, or being held by their family members.

Infrequent or prolonged menstrual periods, excess hair growth, acne, and obesity can all occur in women with polycystic ovary syndrome.
