My 1 year old LO got taken by my relative without permission

This is not okay regardless whether their intentions are good or not. In this case, I would ask the husband to firmly educate the in-laws that the child is under their care and they have the responsibility to not let anyone else take LO away regardless family or not. Should anything happen to LO at your sister’s house, will they be able to account for it? I feel they should at least give the parents a call to ask for permission even thou they are family. As a mother, I want to know where my LO goes and not when I reach home to find out xxx took her. I might also have plans to go somewhere with LO after work then realize LO not there and have to reroute to go pick LO up etc. Regardless, explain to both sides that you appreciate them having the thought to babysit but you would appreciate if they could at least ask first so you can have a peace of mind as well.
