Teenage daughter what do i do now

hi my daughter has cerebral palsy and is 18 years of age she has now finished full time education i have claimed DLA and now she gets pip she had had DLA/PIP since she was old enough to apply for it at the higher rates for both parts. i am her carer and claim carers allowance and am on income support my daughter is currently part of my income support claim as a dependent now she is 18 and has left education she is classed as non dependent the child benefit stopped last week and income support enquired by letter a few months ago about what she would be doing now she is 18. i have informed them that she has finished her studies and may consider studying from home which would be easier due to her disabilities. i have not heard anything yet in regards to what will happen now she is classed as non dependent. my question is will they transfer her to ESA automatically or will they get in touch for me to apply for her as i am her appointee. she will be unable to work due to her disabilities and at college she had to have a teaching assistant with her for all lessons.

i originally phoned ESA a couple of months ago and they said to check with income support as i would lose the premiums if i applied for esa for her and didn't want me to lose out when i checked with income support they said i would lose premiums so the guy advised me not to do anything until i had too. so does this mean they will contact me now she is fast approaching 19 as I'm assuming she can't stay on my income support claim

any advice on the process would be appreciated
