A quick google pointed me to the Hipp website (not somewhere I would go to for weaning advice). It says "dont give bran to babies and children under 5 years as the bulkiness can impair their absorption of vital nutrients from their food." I think it's just large amounts of bran fill them up without giving any extra nutrition, so I'm sure a small amount in bread wouldn't matter.
Since around 9-10 months I have been feeding DS various different breads from Sainsbury's fresh bread counter. (He is 54 weeks now). One of the kinds of loaves I've been giving him is Taste The Difference Seeded Loaf (he loves it), which contains different flour such as Oat flour, white flour, wholemeal flour, but it also contains bran flour (I imagine it's a very small amount). I read about not giving bran but I just assumed that he can eat the bread that the rest of the family eat. Is this bad? Should I stop or can I carry on giving it to him? A bit confused but just started to worry about the bread I've been feeding him. Advice would be geat, thanks.
