Caring for new lawn this autumn

[dave_y]

Hi all, I laid a new turf lawn in March this year and so far so good apart from the odd bald patch here and there which I'm sure is down to the local cats. I was looking into what I should do for the lawn this Autumn to help it out and it seems that the options are to give feed, aerate and to top dress it. My questions are -

* Should I do all 3 of these? My lawn is only 21 m2 so it wouldn't be too much work.
* I bought some Westland Autumn lawn feed and moss killer and I can now see on the back of the box that it says not to be used on a lawn in its first year - why is this so?

Thanks!
