My DB is 31, has a little girl (My DNiece 5) from previous marriage. DB also has little girl (18 months) with his partner of 4 years. I will call her SIL, SIL adored my niece (5) and treated my niece better than her biological mother. She truly seemed to dote on my niece. My DB then decided to have a baby with SIL (DNiece 18 months) as it seemed that they were ready to add to their little family.
Since the day my DNiece (18 months) was born SIL has acted like my DNiece (5) does not exist, and at best treats her as a though she is a PITA and major inconvenience. To the point where she was brushing DNiece (18 months) hair, so DNiece (5) wanted to be involved and asked if she could have her hair done next and SIL just said 'No'. As small as that seems its other little things like not involving DNiece (5) in games with her half sister. She is even trying to exclude her from major family events.
Things have come to a head as SIL has stated that she loves Sundays and cannot wait for my DB to take DNiece (5) home after her weekend stays and she looks forward to it more than anything else.
I am gutted. For my DB and my DNiece (5) as everything seemed perfect and happy until SIL changed her tune so massively. My DB doesn't know what to do for the best as he doesn't want 2 children from 2 broken relationships. He confides in me and cannot seem to find a positive solution to this mess.
I also want to point out that DNiece (5) is an absolute angel all of the time. Even if she was not surely no child would ever merit this treatment?
So WWYD?
