For anyone who wishes to read, also mentions coeliac disease. I'm not sure what I'll yet with Louis - I was introduced to purees etc at around 4 months but was also breastfed till I was 22 months... I've no allergies, food intolerances etc. Each to their own, I think mums know what's best for their babies
Its 'recommended' to eat 5 fruit/veg a day, exercise at leats 30 mins a day, split your food into the 5 foods groups, dont have a BMI over X, etc.etc. The list is endless. Therefore, your make your own choices, and that of baby. Seriously if its 4 months or 6 months, its what works for you, really WHO CARES!
If someone here posted that they only have one portion of fruit a day or is a vegetarian (i.e. not getting all food groups) would there be so much of a debate...?
That's a bit of a strawman argument. As an adult, you're presumably educated and knowledgeable and making decisions that are impacting your own health and well being, and not that of another human being who is incapable of making that choice or decision for themselves.
Also, meat is not the only way to get protein and beans, nuts and eggs are included in the protein 'group' so Vegetarians are more than capable of meeting all of their nutritional needs while still following the 'guidelines.' There are also a lot of non dairy & meat foods that are iron or calcium rich and in several cases (with calcium at least) contain more than dairy and is better absorbed by the body so is actually more beneficial.
