Chocolate weetabix and Nutella in porridge 
I don’t do any exercise. I’m also knackered from work and have loads of planning and marking to do so rarely get much downtime so I can see how that would pan out.
But I still get DS to swimming an son his bike. Also parks are the best place really for him and toddler DD to run around.
But really we just don’t have that much crap. Mine would hoover biscuits and cakes if they could. And so would I (I still do with my secret stash
)
They have 3 options for breakfast: plain weetabix/ready break/oatibix flakes. They put a small spoon of honey in the weetabix or porridge and chopped up fruit like strawberries. On
the weekend they get croissants, sometimes chocolate ones or pancakes.
DS always has ‘pudding’ with his school dinners anyway like cake which I’m always a bit baffled by.
They have fruit after school. Loads of it. Maybe some toast too. Dinner at 5.30.
I do have a ‘snack’ drawer which has those baby snacks type things: bear paws/claws, fruit bakes, oaty bars etc. Mainly for 4 year old DD. She normally has one after nursery.
Neither eat much veg which is a constant worry for me esp v fussy DD so I do keep a fairly tight lid on what they eat. But they do get a biscuit or a piece of cake a couple of times a week too.
A Sunday ‘tea’ of scones and cakes with tea is a favourite
You’re in charge. Put out food she likes that is not junk. And make sure she has something filling after school. Mine are starving. And maybe get her dad to sit with her for a bit. It’s a bit sad coming home from school and not being able to chat to someone about your day.
