Firstly..............If night waking for a feed doesn't bother you, then it is fine!

This is our story.....
When DD1 was 9 months i decided i was exhausted and didn't want to get up to feed in the night anymore. So when she woke, i got up to her, picked her up, cuddled her, rocked her, walked with her until she settled. When she was asleep i put her back down. Yes it took an hour or so the first night. But the next night she settled again much quicker. And it improved from there. I think by about the 5th night she wasn't waking for a feed anymore. So i guess in our case she did need a little help. But i am not sure of a definate answer to your qn..... maybe she would have got there on her own, maybe not.
