The DWP Decision Maker should take account of all evidence presented, however, they are entitled to make their own decision as to weight they assign to it.
You'll need to show you have had Care needs for at least three months and will require care for at least six more. The former may overlap with your care of of your child, so you need to think how you might (you don't necessarily need to), explain this in your submission. If it is your intention to continue to care for your daughter, then you will need to address this as the two may be seen as incompatible.
