There are a few items I've found really helpful for my 8 month old.
The bibado bibs are great. I highly recommend them. I'm doing baby led weaning with my first dd so I don't need much but I've found the baby vital spoons good for feeding her weetabix, yoghurt and porridge. The brand skip hop do handy bowls with lids for taking out on picnics and when you go out to friends houses (now that's allowed!!).
I just put the food on the high chair tray - I keep the bowl with the food in front of me and put more on the tray as she eats. I plan to buy one of the fancy bamboo plates with the suction pad when she's older and doesn't find throwing things on the floor so much fun
.
A pvc mat for under the high chair to protect the floor is helpful.
I bought a good mid range hand blender but have barely used it as the blw was much more successful than purees.
A sippy cup. You can google best sippy cup reviews to see which one your dc might like best.
What mummy makes and weaning made easy are good weaning books.
I've recently discovered the pocket snack booster high chair which is great for taking to others' houses, restaurants and on holidays.
