Yes, if the reference to quote 2 follows directly from that to quote 1 and is on the same page, then you cite the full reference to quote 1 then just cite "ibid" for quote two, which tells the reader that the reference is to be found in the same place as the previous one.
I would just put it once so, e.g. in text "Children's social development is important" (DCSF, 2008) then "Children need to play to learn" (DCSF, 2008)
Then in reference list- DCSF (2008) The Early Years Foundation Stage, London: DCSF [Online] Available at Web address here. Accessed on: 12.04.11
Theres no point putting it twice unless there's page numbers which there isn't on web pages
When i was doing references for my biology coursework I put numbers next to the things I'd sourced. In the bibliography, I put the number then the page on the website/ book and author and date. If there was one thing i got two bits of info from then i just put the number twice in the text and once in the bibliography.
