ok, to cut a long story short, my partner's parents have weekly contact with our son arranged through a court order. this itself has not been without problems however more recently my son (3.5) has informed me that he has been left with other people both in the grandparents home and in another person's home. the 1st time was when they left him with their two daughters whilst they attended a funeral. at the time i requested that i be informed before they leave him with anyone other than themselves. i got no response to this. however this weekend my son told me that he was left with their daughters boyfriend at his house while the grandparents and daughter went away somewhere. he didnt know where. i have never met this boy/man and dont even know his surname. my son has mentioned him before and the fact that he has been at his house, he has also returned with toys that he says this person gave him. really the advice im looking for is whether i am within my rights to disallow this in future. i dont want my son to be left with people i dont know as i would never do this myself. can i do anything legally that will forbid this. the fact that i am not informed of this suggests that they know i wouldnt allow it. if anyone can shed any light i will be most grateful.
