#Babyfever is a colloquial term for the intense desire to have a baby.

  #Oxytocin (Oxt) is a peptide hormone and neuropeptide. It is normally produced in the hypothalamus and released by the posterior pituitary.[3] It plays a role in social bonding, sexual reproduction, childbirth, and the period after childbirth.[4] 

Oxytocin is released into the bloodstream as a hormone in response to stretching of the cervix and uterus during labor and with stimulation of the nipples from breastfeeding.[5] This helps with birth, bonding with the baby, and milk production.[5][6] 

 In the prairie vole, oxytocin released into the brain of the female during sexual activity is important for forming a pair bond with her sexual partner. Vasopressin appears to have a similar effect in males.[61] Oxytocin has a role in social behaviors in many species, so it likely also does in humans. In a 2003 study, both humans and dog oxytocin levels in the blood rose after five to 24 minutes of a petting session. This possibly plays a role in the emotional bonding between humans and dogs.[62]

  Limerence is a state of mind which results from a romantic attraction to another person and typically includes obsessive thoughts and fantasies and a desire to form or maintain a relationship with the object of love and have one's feelings reciprocated. Limerence can also be defined as an involuntary state of intense romantic desire.
