Currently on holiday with my family and another family (old friends) they have 2 older children same age as my kids and they also now have a 6 yr old. We have holidayed with them before but not since the youngest was born. Youngest is ND (autism and suspected ADHD). My son is 15 and autistic so I know about ASD but there DD seems out of control and we can't cope with it. She swears spits hits and throws furniture if she doesn't get her own way - there is no routine and she basically gets what she wants - she slapped my DD earlier today and called her a f b because she didn't want to go in the pool with her - my friends answer to this was you cannot say no to her - if you don't do what she wants she kicks off so we have to let her do what she wants. My friends DH and 2 older kids can't cope with her so they go to the beach and take my 15 yr old with them - I prefer being by the pool so I stay with them and my DD 17. We honestly don't know what to do as our holiday is being ruined by a 7 yr old. She threw my bag in the pool yesterday and I was fuming. We are trying to do stuff without them but they seem to be constantly appearing - they never raise their voice at their DD or tell her to stop as negative language makes her worse. Last night their 15 yr old told my son that she has been permanently excluded from her primary school and she currently has no school place from September - I was aware she has had several exclusions for violence but only short term exclusions but her parents have not mentioned to us about the exclusion. My DH wants us to cut all ties with them until they start parenting their child properly. We are only 3 days in to a 10 day holiday and are tempted to fly home to get away from them. I feel so bad as I am an SEN parent myself but they won't take any advice from us about maybe having a routine and setting boundaries. I so feel for them as they are completely broken by her behaviour but I don't actually know what I can do to help.
