When I took my young lad camping for first time by our two selves it was with a group of friends and I was criticised for letting him basically eat what he wanted for tea. The rest of us tucked into a communal spag bol but all he wanted was jam butties. The way I looked at it and told them he’s on holiday for a couple of days, he can eat better at home but for a day or so it isn’t going to cause any harm. More about being happy and I can see you have that sorted.
