Me, DH and DSS moved in to our new house Friday. The house is lovely and doesn't need much doing expect a paint if we can be bothered.
It has a big garden in which the previous owner had a swing set, shoot and pond. As DSS is a teenager we weren't too worried about the pond so haven't drained it or covered it.
DSis has 2 lively children under the age of 5. DSis is very lax in discipline and lets DNephews do what they want. Both mine and DH's family wanted to come over to help with the move but we asked them to leave us until we are settled. We are still unpacking.
DSis has turned up unannounced when I was out. DH let her and the 2 kids in. DH told her not to let DN in the garden as it's not safe.
I got home to DSis screaming at DH and DSS as DN 4 fell and cut his head. Thankfully it doesn't look to bad. Apparently DH went to the loo and DSis let the kids out into the back garden and then stayed inside. DSS noticed they were out by looking out his upstairs window. DSS shouted DH, then both went down stairs to DSis. Dsis was annoyed that DH told her off for leaving the boys outside on their own. DSS went outside and that's when he discovered DN had cut his head. He may have tripped on the path.
DSis blamed DH then me. She started shouting which upset DNs and DSS. Once I knew what happened I said she shouldn't have let them outside and she should have been watching them. DSis thinks that as she is a guest, DH and DSS should have been more aware that DN could have fallen outside. This is even after DH told her about the pond and not to let them out. DSis has now taken DNs home.
I have had phonecalls from DM and DBrother saying we have upset dsis. I, DH and DSS need to apologise. Aibu to not want to apologise and that DSis was at fault.
