Telling pediatrician we cosleep...

I have been bedsharing with my 6 month old following the Sleep Safe Seven because we truly had no other choice due to his refusal to sleep anywhere else. We have a pediatrician appointment tomorrow and in unsure of if I should tell her. We already do delayed vaccines so I feel like she's critical already and don't want to give her any more reasons, but I would like her advice on how to get him sleeping on his own too. What to do?
