Been here a while but name change regularly.
LO with us since summer 2013. He's now 4.
SIL was married but separated last year. It has emerged that they were having problems for a long time but stayed together when our LO was placed because they thought it would be difficult for us (we had no idea at the time). What actually happened is that LO got attached to an uncle who subsequently dropped off the face of the earth which has taken some explaining.
SIL has now been seeing someone for a month and is talking about bringing him to a family do at Easter, so after she's been seeing him for 2 months. I am uncomfortable about this because it still seems a bit early - it could be yet another person who disappears out of our LO's life if things don't work out. However I'm not sure if I'm overreacting. What are your thoughts please?
