Will I lose my transitional protection if I stop receiving carers allowance

I currently receive the transitional protection on my UC payments as well as the Carers element. I care for both my daughters but only receive Carers allowance for one of them. I am considering giving up the carers allowance, as my own health is deteriorating & I’m now struggling. I am however concerned as to whether it would be classed as a significant change & therefore cause me to lose the transitional protection. Has anyone got experience or knowledge on this that could advise please?
