I've always been of the opinion that breakfast is the most important meal of the day.
9yo is very in to computer games (Wii & Minecraft) - this is relevant.
He usually gets his own breakfast and eats alone (reading a book usually) while I get ready upstairs. if he has eaten breakfast and got dressed and ready to leave by 8am he is allowed TV or a computer game until it is time to go (8:30)
On Friday when I came down I realised he hadn't eaten breakfast but had faked evidence of breakfast (little bit of milk in the bottom of a bowl) but hadn't eaten. he had forgotten a spoon and there was suspiciously no cereal scattered on table & floor. we had a very serious talk about lying. he had done it so that he could have time on the Wii. at 8:20 he decided he was hungry after all and had a bit of breakfast and all was well.
Today he has refused breakfast again but at least he is being honest about it.
(1) how worried would you be about this?
(2) if he doesn't discover any hunger should I make a packed breakfast to take to school or is it better to let him discover what it's like to have low blood sugar at school?
