All of my grandchildren have been weaned this way, and it worked great for all of them.
The youngest is very wary of new foods, and I think would have been a nightmare to wean by the spoon-feeding method.
The beauty of baby led weaning is that the baby is in control of what they put in their mouth. If the first taste isn't to their liking, a spoon fed baby will often refuse outright to accept another spoonful, whereas the baby in control of his or her food will often try another bit after 'playing' with it and getting used to its feel and the smell.
No pressure should be put on baby.
I highly recommend reading up on the method before you have to start this with your DGC, to find out how best to approach it, and how to minimise the risk of choking. Much of it is common sense, but there are sure to be things that wouldn't occur to you,
Where my own DGC were concerned, the only downside was the mess, but that stage didn't last long.. In every other way it was great.
