If you knew me in RL I can assure you you'd know I'm not one of those mums who denies reality, if my dd was bett overweight I'd bloody know, I've eyes and common sense!
once I make an appointment with the gp I will report back as dd has been to 2 consultant led health checks in the past 12 weeks and not one of the consultants or nurses raised any concerns. This is allergy related she has skin conditions, diet / weight has never been mentioned.
Portion sizes are normal child sizes in this house, side plates used, her average daily diet is something like,
bowl of cereal usually shreddies in plastic kids bowl, she may have porridge, or weetabix, all around a 30g serving, glass milk or sugar free squash
School dinners - whatever she chooses
Pick up from school - I don't bring anything only on a Friday when it's treat day so will be either bag of crisps OR chocolate such as a Milky Way or magic stars, the small size - this is only on a Friday before the jury starts judging, orhervsays its apple / cheese pieces, a small bunch grape (around 8-10), and only if she's doing after school activities.
Dinner is usually at 5pm,
the last 3 days have been - homemade lentil soup in ikea small bowls - the 40p ones and a cheese toastie, 2 slices bread, cheese about matchbox sized - no pudding but hot choc before bed at 7
Last night - two scoops (ice cream sized) mash, one cod in butter sauce - the Ross ones, 3 broccoli florets and tablespoon or so of carrots, glass milk
Night before last - homemade lasagne a square string the size of palm of my hand, banana milkshake which is homemade using 1 banana and a glass of milk.
I'm using full fat as have a 16 month old, dd usually has glass in the morning and cup at night before bed, should I know use semi skimmed?
Snacks - I don't usually have crap in the house as dh is a clean eater and don't touch it, I've no willpower so buy my own treats 
Dc dont like things like haribo as but do like chocolate and cakes but unless we buy in the weekly shop or as a one off treat they are not usually in the house.
Snacks only at wkends really as at school mon - fri and I work and dinner is served at 5ish then a milk or hot choc before bed.
Calling go tomorrow as I want to sort it out, I was extra vigilant yesterday on her portion sizes, this is not something I want to escalate, I don't want a fat kid but at the same time this is my child we are talking about so I will be sensitive.
