^WTS. When my eldest was small Hipp and other companies had some of their baby juices, flavoured waters (yes flavoured water foe babies) and teas say from 4weeks/1 month on the packaging even though this could be really harmful. The government clamped down on it and they stopped, this was only 9 years ago now when the weaning age was 6 months. In other countries with less strict laws baby food companies who sell products here in the UK label their products as suitable from birth or 4-6 weeks, nestle who now own SMA are one such company, Hipp are another notorious culprit. Just goes to show 'organic' doesn't mean ethical.
Labelling laws can be quite difficult to change and the baby food companies are very wealthy and powerful so will fight the government in the courts, it doesn't mean that what they are saying on their packaging is safe advice that is up-to-date and/or correct. If you look at the small print on the rusks it did say last time I checked that gluten is unsuitable for under 6 months but knowing these companies they may have removed that advice now if they can get away with this. All they care about is their sales. There is a very small amount of research that suggests giving gluten between 4-6 months is safe, however this research has found massively increased risks where gluten is given before 17 weeks and the majority of research suggests that waiting until 6 months is safest. This is why most allergy charities including those who deal particularly with coeliac disease strongly advise waiting until 6 months before introducing solids but if you must start earlier at least avoid gluten until then xx
