For those who have fallen in love with the person of their dreams, it may be a package deal when it comes to the relationship. They might still have their children with them, and becoming a step-parent might be part of the bargain when it comes to marriage or living together. Being able to make the adjustment can be a rocky time for everyone, and it can deeply affect how the relationship will proceed in the future.
A successful adjustment might seem easy at first, but it can quickly devolve when discipline becomes a necessity. The relationship with their parent can dissolve as the children attempt to ensure they will not be told what to do or how to act by someone who is not their biological parent. Being able to gracefully become a part of a blended family will take work, and fitting in together will take special effort on the part of every person involved.
