Google Adsense after post 1 and 2

Hey,

I am trying to add Google Adsense to wrap in the first post (with the div float tags), which I have already done, and then after the first post I would like another Google ad there.

I read how to do it at https://www.lancelhoff.com/2007/02/28/adding-adsense-ads-between-posts/ , but I don’t know how to do it if I want to add more then one ad to the homepage.

Thanks!
