i was just about to ask where are the lemons in the lemon curd recipe! then you updated! they sound yummy.
mine wouldnt normally get yog and cake on the same day, and we occasionally get those corner yogurts as a treat but we have just come back from 4 days staying with relatives and they had one every dinner time as a'pudding' we rarely do pudding in our house.
i think it sounds ok, technically three 'treats' but it is the holidays, hell not only did mine have the corner yog every day they also got a small packet of haribo each day, again courtesy of relatives. but they also ate lots of fruit and veg as normal.
today mine have had
cereal (normally one or two weetabix with a handful of rice crispies or cheerios on the top) or toast or porridge (cant remember which child had which)
snacks of a cereal bar, apples, bananas, small oranges, grapes and some more cereal but dry in a bowl! carrot and cucumber sticks
lunch was cheese sandwiches or crackers with cheese and pickle, grapes and home made mcvitites type biscuit each, plus water to drink.
dinner was a chicken, bacon casserole done in the slow cooker with toms, mushrooms, red wine, shallots and served with mash, carrots and green beans.
the snacks have been here and there throught the day, they can help themselves to fruit and do so and the older three cut up some cucumber/carrot etc for them all to have, they had a bit of hummous with those.
