DLA and carers allowance

I was looking for some advice. I’m currently receiving ESA and PIP. I have the severe disability added to my benefit as a premium.

My toddler has just been awarded DLA. The application was sent in Mid-December 2022 and I rang them up today and they informed me he has been awarded from NOV 2022. It is suspected that my son is on the Autistic spectrum which has caused a lot of developmental and speech delays.

I want to request a MR as I feel they haven’t taken into account how difficult his “night time needs” I would like some support to challenge their decision so any advice/support would be appreciated. I wake up multiple times a night to attend to his needs and it takes him a long time to settle.

Additionally I was thinking of applying for carers allowance. I get child tax credits at the standard rate for him but have been told to contact HMRC to let them know my child is in receipt of DLA. Can I apply for carers allowance (I meet all the criteria) but I’m worried what impact this might have on my circumstances and benefits.

I too have complex medical issues which impact on my abilities but despite all the struggles I do the best to look after my son even though it can be at the expense of my pre-existing conditions.

I’m looking for any advice on how to best proceed with a MR as they feel because a sleep specialist is not involved his night time needs are not high enough for him to get the high rate. Should I do a diary? Also how will applying for CA impact on my other benefits.

Thank you
