Purple quote from ISIS...
"Adding to the pressure on (often already sleep-deprived) parents, popular parenting advice books, and advice from well-meaning friends, family, and other sources can lead parents to believe that if they don't 'sleep train' their baby, he or she will be unable to learn to sleep for longer, or through the night, of his or her own accord. The well-worn phrase "making a rod for your own back", often used in relation to parents rocking, feeding or cuddling their babies to sleep, is an example of this. In response, many parents try to put their babies down to sleep alone, only to find that their babies have other ideas, and object -- loudly! The end result of this process is, in many cases, parents who feel that they/their babies have 'sleep problems' when, in fact, their baby's sleep (including waking at night) may be entirely normal for his or her age, and stage of development."
So carry on as you are, you (and we all) are doing a great job!
