That HIPP site actually has quite a neat summary of what it says are the latest evidence based advice, based on a paper published in 'paediatrics' last year.
I suspect this is probably what the health visitor is talking about - it seems sensible, realistic and practical (and also, you will note, states, as I said in my first post, weaning can begin between 17 and 26 weeks)
This is what it says
In fact, because of the lack of published scientific evidence on complementary feeding and lack of consistent messages, there is considerable variation in weaning practices between different countries in Europe. To try to overcome some of the confusion, a group of European child nutrition experts (ESPGHAN) has recently published a paper ¹ which has looked at all the current knowledge and feeding practices in healthy infants, with the aim of providing a list of conclusions and recommendations for health professionals and Governments to follow when communicating with parents so that more consistent advice is given.
Conclusions
So what conclusions did they come to and what recommendations have they given for the best weaning practices to follow? A summary of these is given below, and are considered to benefit infants and young children not just in the short term but also in the medium to long term:
Exclusive or full breastfeeding for about 6 months is a desirable goal
Complementary feeding (introducing any solids or other liquids other than breast milk or formula) should not start in any infant before 17 weeks, and all infants should start by 26 weeks
The same advice on weaning should be applied for breast-fed and formula-fed infants, even though their dietary needs may be different
It is unclear whether earlier introduction of solids or other aspects of complementary feeding influence later obesity risk
Avoiding or delaying the introduction of potentially allergenic foods e.g. fish, eggs, has not been shown to reduce allergies, in either infants considered to be at risk or those that are not (this conclusion has also been reached by the American Academy of Pediatrics in their recent review of dietary influences on the development of atopic disease²). In fact, delayed exposure to high risk foods may be associated with an increased risk of allergy.
Gluten should not be introduced earlier than 4 months, but gluten-containing foods should be introduced before 7 months of age. Small amounts of gluten should be introduced slowly, preferably whilst a baby is still breast fed. It is thought this could reduce the risk of developing coeliac disease, type 1 diabetes and wheat allergy
Babies reach different feeding milestones at a range of ages and so appropriate foods should be given for each baby. However, it is important to remember that there is a critical window for the introduction of lumpy foods, and if these are not introduced by around 10 months of age, it may increase the risk of feeding difficulties later on
During complementary feeding, breast fed babies should receive at least 90% of their iron requirement from complementary foods and this iron should be sufficiently bioavailable.
Cow?s milk is a poor iron source. It should not be used as the main drink before 12 months, although small amounts can be added to weaning foods.
Infants and children receiving a vegetarian diet should have a sufficient amount of milk (about 500ml), breast milk or formula, and dairy products in their diet
Vegan diets are not appropriate for infants and young children.
More research is needed to clarify the effects of different foods and/or nutrients on growth, development, and health during this period of rapid growth and development.
