I also get stressed out deciding what to give my 4 DGCs.But after being made to eat foods as child and being physically sick decided from start that I would never force food on them or blackmail them with no dinner/no desert.To make life easier I do try stick to the limited foods they all eat. 1 GS eats no veg 2Gds eat brocolli and 2Gds baby sweetcorn.I have 2 nibble trays 1 with an assortment cherry tomatoes,cucumber,celery.raw carrot,fresh beetroot,humous,cocktail sausages.At mealtimes they either eat all dinner or choose to add from the healthy nibble plate.The 2 nibble plate has tube yoghurts,mixed seasonal fruits and bun,cake treat each.Couple of GCs prefer to have ice cream/lolly instead of cake.When we have cleared the table I leave the nibble plates on side and before they go home some 3 hrs later, very little left.Not ideal but I know they cannot be hungry.Then the start of 2 GCs lunch boxes 1 ham mini wrap, cucumber,celery, tomato on chicken satay stick.1 GC now dislikes yoghurts,choice breadsticks,fries.popcorn etc,mini snack pack biscuits,fruit.
Then DH wonders why supermarket bill is so high.
