Agree. I suppose the women I met who did the extended BF (way beyond 6 months) were also the ones that were pretty set on not introducing any solids until 6-7 months.
Each to their own, but I do feel that some babies are definitely ready for some solids before then.
I guess as a fairly mature mum - and I've worked in research and did lots of research when I was pregnant - I didn't feel compelled either way necessarily on the solids introduction period but knew to trust my own babies and instinct. I did baby led weaning; introduced taster portions from 4 months.
We have asthma and allergies in the family (my DH is severely allergic to animals, pollen, dust, had asthma etc etc; my mother too - weirdly I was purely formula fed and have none of these, but that's just an aside).
But, on doing my own research (this was back in 2006), I did not heed the advice about not eating nuts or fish (if cooked properly) etc etc as I had already read about some of the research that was the early basis of what has found in the EAT, LEAP studies etc. It's about introducing allergens, essentially developing immunity (of course peanut allergy research is now very focused on desensitisation therapies).
I felt strong enough as a person to just go with what I felt was right, especially as a couple of the health visitors I met simply hadn't done their research, but understand they had to 'toe the line'. But I saw so many mums who were sleep deprived, with hormones going wild who felt 'terrorised' by their health visitors for not BF or introducing solids earlier.
Neither of my kids have allergies; neither are overweight - I did introduction of solids at 4 - 4.5 months, which is when both of them started showing interest, reaching for food, and bringing it to their mouths whilst doing chewing motions.
