Hi cantbelieve, sorry to hear that you've had such a sudden diagnosis. DLA is issued at 3 rates for care: Low, Mid and High and mobility: Low, high.
The rates are as follows, for 2012:
Low rate care:£20.55
Middle rate care:£51.85
High rate care:£77.45
Low rate mobility:£20.55
High rate mobility:£54.05
Carers allowance is currently £54.45 per week
To get Low rate care, you have to show care needs of over 1 hour per day in total.
To get Middle rate care, you have to show that care needs are frequent throughout the day, or at night.
To get High rate care, you have to show that care needs are both frequent throughout the day and required for a prolonged period at night, or frequent shorter periods throughout the night, on at least 5 days out of 7 each week.
Any care that is typical for a 10 month old baby will be disregarded, so you will need to show that the time you spend caring for him/her is in addition to the care that you would normally give a baby.
You won't be eligible for Mobility until your child is 3 years old. However, if you have bulky equipment to carry, then you may be able to get a blue badge before then.
To qualify for carer's allowance, your child will need to receive middle or high rate care.
You will find that if you are eligible for tax credits, these will go up if you qualify for DLA.
