Help me work out how to navigate this please.
DHs mum and partner have suggested we go camping with DHs brother, his wife, their two kids and DHs sister. Over my birthday.
DHs family have...tensions. We've rarely all been in the same place in 10 years. We aren't allowed to in laws parents (massive) house because it's too much upheaval for them. The last time we all got together was after a funeral at instigation of sister in law. It was on condition that we stay in the garden (helped by covid but not necessary under eased restrictions at the time), fine but a bit strained.
This camping trip is by a big lake. There are canoes involved. The 3 kids are all under 8 and none can swim. I am an anxious parent. I recognise this tendency and do pretty well at keeping it in check most of the time. I'm good at letting DS take risks as a young child should. DH is pretty hap hazard with safety. His mantra - "It'll be fine" - is basically an act of faith that also serves to shut me up and make me feel like an idiot for feeling anxious when I see my son doing something I genuinely think is too dangerous (floating down the river in a canoe with no one near him, running around on top of a cliff). This sets my anxiety off (I have PTSD after a near fatal birth).
Recently, DSs cousins were left unsupervised (by MIL and DHs brother) in their garden which has a river running through it. The youngest fell in. Unseen by a grown up. The oldest (7) somehow fished him out. The "It'll be fine" mantra seems to be a family mentality.
I don't really want to spend my birthday on this camping trip. I was never asked. I don't think 3 days in tents with 3 young kids by a lake and a family that find it hard to spend time together is a recipe for success.
Being underslept and not listened to is going to make my anxiety 10 times worse. I can't suggest DH and DS don't go. They deserve some fun with their siblings / cousins. If I don't go, I will worry about DSs safety.
I've suggested to DH we go for less time. He thinks I'm being pessimistic and is treating me like a neurotic woman.
How would you handle this so that DS doesn't miss out on time with his cousins, DH doesn't think I'm a cow, and I don't spend the whole 3 days being a nervous wreck?
