Post DC I've also been prone to leaks on sneezing/coughing etc
With DS I had large episiotomy and ventouse and things have never felt the same downstairs.
Recently DD got invited to a trampoline party and one of those indoor jump park things. I realised I've put off taking the kids myself as there is no way I could do it - I would just wet myself.
This week DD was trying to skip with a rope I offered to show her, jumped about 10 times and needed clean knickers!
I do pelvic floor exercises is that all I can try as it's bloomin irritating
