Don't understand why Lauren is upset with Phyllis wanting her grandbaby?

Lauren feels that Daisy needs to be punished for what Daisy put her through. Just as she thought she was putting that all behind her, Phyllis had to lure Daisy back to town, to try and get Lucy, causing Lauren to relive the whole nightmare again in her head. I don't blame Lauren and everyone else to be mad at Phyllis for what she has done. Phyllis doesn't care about anyone but herself, and she will step on anyone to get what she wants, even her own son. I truly hope that Victor can take her down for what she is doing.
