weetbix (the kiddies one) with sultanas and sometimes chopped up dried apricot generally work for us ... after a battle getting DS1 to consistently eat brekkie, he's happily eaten this for the past couple of months (maybe longer). And DH and I have found the stogier the weebix mix, the easier it is for him to feed himself Er, not that I let it get so stodgy it's yuck!

Brekky is the one meal that caused us pain! Good luck.
