Blast!
It won't make you feel any better, but I've just had a weekend of trying to persuade my 2 year old that hopping off Mum's lap whilst still attached isn't a positive thing.....
If your LHS is much worse could you slowly wean him off that side? Or could you be super-mean and wrap him before feeding so he has less wriggle options?
I think that seeing a LC at this point could help you work out what to do as well - or if your MCHN is good at this (some are and some aren't) then they may also be useful.
