I was the same - ie why the rush?
But I have ended up giving him tastes since 23 weeks - starting with literally a few mouthfuls of homemade fruit/veg mush every other day - and I've been astonished at how ready he has been.
He was sitting well and reaching for and putting things into his mouth. I was still unconvinced at that point but when he started mimicking our chewing one night I did wonder.
So gave him a tiny bit of carrot and he swallowed with ease - no tongue thrust. A couple of days later we tried some more and he was grabbing for the spoon to feed himself.
Shortly before this I'd taken him to be weighed and was startled to see he had only put on half an ounce in a fortnight. I was thinking of taking him to gp to query reflux (he has always been very sicky) but health visitor said 'I wouldn't worry, it looks like he's getting ready to wean'. My mum and I were a bit gobsmacked by the vagueness of this but hv said to start at around 24 weeks.
So for me, was a combination of factors. Including wanting to get him at least part weaned by the time I go back to work. And seeing some research that calls the 6 month rule into question plus my son's apparent readiness also were significant.
In all honesty, it's a bit of s faff, and I still don't actually understand why we wean at 6 months anyway if the 'food before 1 is just for fun' bollocks is true - although I understand it is important for speech development.
Tl, dr; was in no rush but reality got complicated.
