XH and I have 2 DD (14 & 10) we've been divorced for 6 years, he sees them every other other weekend and has them overnight once during the week every fortnight, so all together he sees them 6 times a month.
Every summer he takes them away for 2 weeks.
DD2 (10) has Autism, she's non verbal except for a handful of words but she can understand 90% of things told. She's hypersensitive, can't handle having her hands dirty or wet and is very aware of light and sounds, so struggles to sleep. She's also not very good with new people
XH who's taken them away before and is perfectly aware of DD2 struggles, has just booked them a camping trip for a week with his entire family, his parents, aunt's, cousins etc.
A camping trip! Where they sleep on the ground and inevitably get dirty and wet with a large group of people that DD hasn't seen in years.
If I could believe that XH would keep his attention on DD2 throughout the trip, make sure she was comfortable and happy as she can't really verbally communicate then maybe I would consider it, but it's usually left to DD1 to handle it when they go away with him.
We don't have a court order, it's just an informal arrangement, but I'm not agreeing to this.
