Welcome to FamilyHub and thanks for your post, though I’m sorry to hear you’re having a difficult time with your daughter.
I’m not a parent so I can’t empathise, but I’m sure countless others out there have been through the same thing with their little ones - you’re not alone.
Have you had a look at all the information provided by FamilyLives? FamilyLives is a national family support charity and provides help and support with all aspects of family life. They have lots of information about the different stages of your child’s development. Have a look at their website, or you can give their helpline a call on: 0808 800 2222
I hope this helps, and best of luck!
