Simple advice op?
You sound tired, brittle and overwhelmed. Five and two are hard work. But an incredible fun age too. You don't sound like you are enjoying them much. Are you? It doesn't sound like this is about the pool, but about much bigger. How to get your children to comply.
You have high standards of parenting, as I do.
There's a difficult transition from absolute control of babies to helping our toddlers & children learn appropriate behaviours & to evaluate risk themselves. I remember clearly a picnic with my then toddlers through gritted teeth where. We. Are. All. Going. To. Have. A. Nice. Time!
They will continually be set targets, in behaviour, and challenge, and education, and sport as they grow by us as parents and teachers, and themselves that they must be allowed to fail safely. I'm not talking about letting her drown. I'm talking about giving her a job eg of carrying the towels.
Here's what has worked for us, with boy/girl/boy, now 14/12/9. Less than 2 years btwn big 2,but little one was Dangerboy by nickname for a reason) autism ADHD). Daughter did as she was asked. House rules as for all, from talking:
- Listen and follow instructions
- Use manners and don't be rude
- Take care of people and things
- Have fun
Asked politely to do something - once
Next told firmly to do it - 'name X, reminder, I've asked you once'
Next, Made to do it - 'name X, I've asked you, and told you, do I have to make you? if I have to make you, you will go into time out'
Except for any physical harm committed by them deliberately*, in which case, remove from harm, time out, stay with them, explain why you are unhappy with behaviour.
*we used to say 'we don't hit or kick' until clever kids retorted 'I didn't, I slapped him😕 so the list became ridiculously long' we don't hit, kick, slap, pinch, pull hair or otherwise hurt in ways not mentioned'
Always give an opportunity to correct behaviour, and always check both hearing & understanding. Eye level communication, all that good stuff.
'children who just don't listen/obey' can often be those who have a sensory processing disorder. They genuinely have not heard/registeted what you've said.
Please don't reject some of the advice you've been offered by pp. Their advice, and all the effort you are wanting to spend is actually all intended to same effect - your kids having fun.
