Gosh that must be stressful leaving with those restrictions, hope you get a place quick and you are not too far on the waiting list.
Breakfast is easy stuff like toast, weetabix, ready brek, porridge, fruit, yoghurt.
Lunch, leftover dinner from night before just simple stuff like boiled potato, mash, boiled or steamed vegetables, when you have it for dinner do a few extra and you can use for the next couple of lunches or dinner. Put some fish or poultry with it or eggs. If you have no leftovers then maybe scrambled eggs, beans and bread, or egg soaked on bread or sandwiches or tuna pasta or other pasta.
Dinner just give him what you eat for dinner, if he has the same as you (provided your food is not low fat - just have healthy foods like veg meat, food that is home cooked which has no added salt in there) apparently if they have the same as you and loads of different foods they will not be fussy eaters.
Even if you and LO have same meals then that will save you time in the long run cos at least baby will be used to the food u eat and you only have to make one type of meal.
