hi lostin
do you have a qualified teacher of the visually impaired (QTVI) yet? Do get the eye unit to refer you or ring your council and refer yourself, they usually come under the education service somewhere, often as part of a sensory impairment service. There's also the nbcs victa and look that are worth looking at. That's assuming you're UK based 
I didn't see your weaning thread, sorry. It's good to talk through everything you do, even if she's not yet understanding, as she's so young keep the language simple and consistent so you might say, 'dd (use her name so she knows you are talking to her) food time', every time you go to prepare food as she won't be getting the visual cues that a sighted child would that food will soon arrive. It depends on how much vision your dd has, if she has some residual vision then think about colours and contrast, so if you have a white piece of bread then put it on a red plate for example to give her the best chance of seeing it, you may still have to guide her hands. If she has a white high chair tray then some really bright cutlery, plates and bowls would be good, ikea do some cheap and cheerful stuff.
If she has no vision or is likely to loose vision, or you just fancy doing it then objects of reference are a good way to go, so you'd give her an object that you give every meal time, eg a spoon, so that when she has a spoon in her hand she learns that food arrives. That works with plenty of other things like a plastic duck might indicate bath time. It allows her to anticipate what is coming next which again, sighted children get from watching you running a bath or seeing you get a towel out. So once she has the anticipation that food is arriving, you can run her hands round the outside of the plate of the bowl so she knows where the food will be and guide her hand to the food itself. Same when food is dropped on the tray, guiding her hand round till the food is found until she learns the process herself. Of course it would be easier to place the food directly into her hand but it's good to be thinking about independence and teaching her that when the food is dropped she can search round with her hands and find it.
my dd3 (7) has some residual vision that she uses really well when she wants to, unfortunately meal times she can't be bothered and rarely looks at her food, it still gets messy
