As a lone parent the biggest help was to get my nanny and my sister on board with my views on feeding my son and they are, they also see the results and the changes and so they are “believers” now!
Some of the strategies that helped: Accountability, visual timer, presenting dessert with the meal, family style meals, owning division of responsibilities, never talk about how much J eats and what he eats, food play, developing a routine around meal time (wash hands and set the table).
