Hello JM and welcome of the forum.
You may not be aware that you have what could be your full name showing. If you would like to change this please have a look here.
My full name is showing, how can I stop it. If you are new to the site and have not yet had a look our PIP guides I think they will be really helpful for what you are doing at the moment.
PIP resources But as to your question - yes you can send in separate sheets, and I would do that rather than stick them into the PIP2 booklet.
The only rule is that each sheet must have your name and NI number on the top, and we recommend that you also number the sheets to hopefully prevent any of them getting lost. E.g. page 3 of 4
I nearly always draft what I am going to put on the forms on my computer first. If it is a short one or two sentence response I then copy it over onto the form, otherwise I just write in the box 'see separate sheet page X'. I also try to be nice to the assessor and clearly label each section with the same title as is on the form.
I read on here that Gary recommends then loosely attaching the sheets to the form, in a way which can easily be separated so that the DWP can scan the documents. Personally, I just slip them into the middle of the booklet.
I hope this helps,
Catherine
