I'm really glad I read this thread and you guys educated me on this way of feeding. My little one still loves his 'mush', but I've been encouraged here to give him much more finger food and let him experiment more with his food, have fun and get messy (it helps that we have a new high chair!).
Tried him on some toast, which I would hitherto have thought totally unsuitable (he's 8.5mo, corrected age 7m) , and he LOVES IT! I suppose bubs have an excess of saliva and it softens easily in their mouths. Has recently demolished the food of the season, Hot Cross Bun broken into chunks. Cheers to All.
