Like his sister (and mum), if you try to get him to eat carbs as soon as he gets up, he's likely to puke them back up 10 minutes later.
No, we don't eat together. I've usually left the house before anyone else wakes. When we lived on the boat, the kids had to be up much earlier (40min drive to school), so I made him reddiebrek. He's gone off that now (see comment above about puking). He might cope with a fryup - although my bank balance might not survive it.
Hmm - I might try getting a variety of nuts and making him a 'breakfast snack' container, that he can grab a handful of before leaving the house.
