Hi, my name is Bostankhan22! Advice my carer daughter applying for PIP

Hi @Bostankhan22 - & welcome to the community. That won't be a problem. Your daughter's own anecdotal evidence as to the functional problems she has doing/attempting any of the applicable activities/descriptors is the most important, as her GP doesn't see her cook, dress, budget, etc., & PIP isn't about any diagnosis.

She can see the activities/descriptors that are looked at with PIP here:  https://www.cambridgeshire.gov.uk/asset-library/personal-independence-payment-descriptors-and-scores-april-2023.pdf
She should aim to give a couple of recent, detailed examples as to the difficulty she faces for each applicable descriptor, i.e. when did it happen, where, what happened, did anyone see this, & were there any consequences to attempting/doing an activity?
She should say if she can't do each applicable activity 'reliably,' i.e. safely, to an acceptable standard, repeat as often as one would reasonably expect, or if it takes her much longer than someone without a disability. See this mentioned at the end of the link above.
You can always add extra pages at the end esuring she puts her name & National Insurance number on each page. She can also ring the PIP enquiry line on 0800 121 4433 to ask for extra time to complete the form, & will be given another 2 weeks without question. Keep a copy of everything 'just in case,' & get a free Certificate of Posting from your Post Office when sending the form off.

This is also a long, but useful read, explaining what the assessors are looking at with PIP.
