What would you like advice on? When to wean? How to wean?
When to wean's easy. If your little boy is sitting up (perhaps with some support), has lost the tongue thrust reflex (poking out his tongue to stop things from going in his mouth and using his tongue to push things out of his mouth) and he can pick up things well, put them in his mouth, chew and swallow then it's probably safe to say that he's ready. He'll do most of these things on the approach to 6 months.
In terms of how to wean, it's personal preference. Some people like purees, other like to get on with finger foods (blw) and if your baby's around 6 months then they're physiologically capable of moving straight to finger foods. In fact, you can kill two birds with one stone by putting a baton of cooked carrot or broccoli in front of him and seeing if he's one able and ready and two, whether blw suits you.
I took the attitude of dd being part of our family and wanting her to enjoy family meals. And as a 6 month old can eat what we do (no honey, no whole nuts and careful of salt/sugar content), I let her join us for meals from the beginning. Her first dinner was a roast. She quite happily picked up, sucked, gummed and chewed potatoes, veg and meat. From that day on she just ate what we ate. No fuss, no purees and no problems. But if you want to puree then there's no reason not to use something like the Karmel book. She's a bit sugar mad though iirc.
The Department of Health weaning guidelines are straightforward and easy to follow if you want something official.
