Why do you want to fix your baby's sleep cycle? Please understand that your baby is a 'normal baby' and nature has designed human beings like that. Some (not all) babies sleep at night and remain awake most hours of the day beginning 4 months of age; and I personally feel that their mothers are blessed.
Next Steps
Let your baby enjoy her babyhood. Feed her frequently. Make sure her vaccinations are up to date. Talk to her, play with her, cuddle her, get her age appropriate toys to play with.
It is distressing for the mother to look after household chores, with a baby who won't let her sleep at night, but then, nature has assigned this arduous task to mother.
Health Tips
Please do not fix anything that is designed to be the way it is.
