i think 2 things, if she has PR in the EU then she can go and live in another Eu state for i think 3 months before she has to start exercising her treaty rights.
if she can't for some reason then it could also be possible she could get the right to access a child living in the uk, but i dont think she can work etc. better trying the euro way.
