Aww....how frustrating to say the least... Maybe try to explain that small amounts is okay..but too much junk makes them have tummy aches?
pack snacks and juice? Send a list?
I think my MIL just loves feeding them sugar all day and sending them home to meltdown..while at her house they are sweet little angels who will do backflips for candy!!
I told her fine..if you must bake cookies at 745AM PLEASE make sure they eat some healthy things before then because they need that first before the sugar rush kicks in.... And BRUSH THEIR TEETH!!!! LOL!
Hope that helps a small bit to know your not alone momma!!
