Oh, it is the same spd. Sorry, I was confused.
If she wasn't feeding herself when you did the original application, it isn't a change of circumstance, and you will be completing another form prior to her third birthday, which will take into account the difference between her peer group with their newly acquired skills. (Ie she has never fed herself, so they will already know that. It isn't a change of circ).
Presumably the issues you are now suspecting may be labelled spd were also present and commented on when you did your initial form - ie we have never called dd2's spd 'spd' in a dla form, but we have commented on the actual problems and what we have to do to support them. Ds1 has some sensory issues as well, but we have never bothered to complete dla for him (he has ADHD, anxiety, aspergers traits and phobias). So for dd2 we couldn't take her anywhere because the noise meant her Moro would kick in (she has retained reflexes) and she would clap her hands to her ears and fall to the floor - this was at about 4-6 and she was using a walking frame, so to cover her ears she would let go and collapse... We then had to carry both her and the walking frame to somewhere safe etc, calm her down, and try again. Supermarket shopping made her scream as the lights hurt her eyes (when she became verbal around five she told us- if we had known it was the lights before we could have fixed it - she just wears sunglasses to the store lol).
She has always been touch sensitive from birth, so dressing/ changing nappy etc was a nightmare and took at least twice as long as a regular kid. We couldn't do baby massage as she was so touch sensitive, but needed to, to try and desensitise her to touch, so the time spent carrying out massage therapy to a screaming agitated bundle of baby, and calming her down afterwards, also went onto the form. I'm guessing you did similar, unless she has only just started becoming sensitive to noise/ light/ touch or sensory seeking? We've never called it spd on a dla form, tbh. They knew what issues she had, it didn't occur to me to tell the, what it was called. (Dla isn't based on dx at all, just care needs, so a name won't really matter?)
So, the feeding stuff (2yos aren't expected to be independent eaters, they are expected to have an adult present and helping) won't change award. Once you complete the update for the age three (to determine mobility award etc) they should take into account that she still isn't - although tbh 3 yos are still expected to have an adult present when they are eating etc. If you have an OT on board (I am assuming you do) self help skills such as feeding are really generally targeted around 3 or 4, so at that point you can expect the OT to start focussing on this - ie they will usually do an updated fine motor assessment, and try and suggest some specialist cutlery that can help. There is so much available, from regular spoons with bigger grips, to curved utensils for children with poor wrist function. They will also suggest lots of exercises (essentially hand over hand training with you behind dd) to model movement of spoon to mouth, in the hope that she will move towards independence.
If she has no purposeful hand function at all, then obviously this will be reflected in your application. (Hand to mouth stuff is very interesting, btw - can she put her fingers or hand in her mouth? It's one of the first ways that babies and toddlers start learning about the world - and leads to understanding as well as promoting oromotor development) they then obviously progress through the 'normal' developmental stages of mouthing objects, if they have functional movement - all important developmental stages.
Dd2 couldn't put her hand in her mouth - so didn't get any of that initial stuff, so we also had to try and gently bend her arm in that direction in an attempt to facilitate it for her - we had varying success!! Obv then we had to provide toys etc for her to try and mouth... Tbh it was all a bit pants as she had v poor oromotor as well as limited fine motor. Anyway, it might give you some idea about how to write up stuff on the form. (We had to feed her at night as her muscle tone was too high to coordinate swallowing and breathing during the day, lol)
DLA forms are notoriously hard to decipher, especially the changes bit. Cerebra has a great guide that will give you some hints too.
