Can be a pain here but I started to do lunch at 11am and it seems to have helped. SO they have breaky about 7am, snack about 9.30am. Arvo tea is at 2.30/3pm and then dinner at 5.30. It seems to be a massive amount of food in the morning and then less as the day progresses. I let them choose one snack from the pantry for the day and they get to choose when they eat it - so tiny teddies or the like but the rest of the snacks are fruit/yoghurt/vege etc. I found giving them control/choice or the illusion of it has helped. Maybe boys are different tho? xx
I've been doing meals at the 11am and 4pm tantrum. Seems to be helping here too!

I feel like I'm saying 'if you don't want a sandwich you can't be hungry' a dozen times a day! Drives me nuts!
