Both of mine have always love weetabix. My youngest has 2 a day pretty much everyday. It doesn't give her any toilet problems at all (it didn't with my eldest either).
I would agree about them filling children up. 2 is excessive really for a 3 year old but the reason i give her 2 is because she actually eats very little generally. If i didn't give her 2 she wouldn't eat any more food during the course of the day so i give her 2 to make sure she actually does eat 1 decent meal a day.
My eldest has always had 2 a day too but he's always had a huge appetite and 2 didn't really fill him up anyway.
