As fatoldladyinpjs says there are 1,000's of knitting patterns on line. Go to your favorite search engine type in something like:
"knit pattern baby sweater"
if there is a term or abbreviation you don't understand go back to your search engine"
"Knit ssk" (ssk = slip, slip, knit)
and a number of different sites that will explain the term will appear. There may also be youtube videos showing you how to do the stitch.
Be aware that not all knitting abbreviations are universal and some may be developed by the author. If it is a good pattern abbreviations will be explained as part of the pattern, especially little used abbreviations.
There is also the excellent help found under the "Free videos" tab at the top of KnittingHelp pages.
