1、先把句子化简去理解
—— I have had the love since I was little.从小时候起我一直都有这份爱.
2、加上去强调副词 ever
—— I have had the love ever since I was little.（从小时候一直到现在）我都有这份爱.
3、给主句的宾语 love 加上定语定语of a whole family
—— I have had the love of a whole family ever since I was little.从小到大我一直都有（对一个完整家庭的爱）
4、最后调整语序,回到原来的句子
—— Ever since I was little I have had the love of a whole family.
