This evening I was astounded to find out LGR doesn't eat Rice Bubbles. He only has Weet Bix for breakfast.
I did manage to get an explanation from him:
"Yesterday Tommy (his teddy bear) told me this is my last day of eating Rice Bubbles. Now I just eat Weet Bix. Until after Christmas."
I'm glad we got this sorted out. It should make breakfast time (if I'm ever around for breakfast again - I left for work at 03:00 this morning ...) much easier.
