Just wanted to add my own experience here. I mix feed my babe, and I have to say (and I hardly dare coz I imagine I may be shot down in flames) that my experience is that as soon as he stopped being exclusively b/f, ds became a much more predictable and lengthier sleeper. I had to switch to mixed feeding for reasons which some of you may remember from earlier posts. I have to admit that I don't have a lot of other experience of babies, my sisters two who were both excl. b/f and a mates two who were both excl. b/f and all of these babes were terrible sleepers. My sister eventually 'sleep trained' her two (another really touchy subject I am daring to venure into, must be the two glasses of wine!!!) and now has two extremely well slept dd's. My mate can't get her head around the idea that maybe kids need to be taught how to settle themselves (and fair play to her, I'm not saying she should), and still struggles (valiantly) with both of hers, youngest ds still waking every two hours at 6 months. I'm not advocating either way, just adding the facts that I know of. Also, and I know that this maybe my final crime of the posting, I just wanted to say that I have just 'sleep trained' my own ds, who is 12 weeks old tomorrow. I know that it is not advocated before 6 months, but although he was sleeping extremely well during the night (from his dream feed at 10 until somewhere around 5 or 6), he was not napping at all during the day, except for tiny little ten minute fresheners. This made him extremely fractious and in my opinion very stressed, he kept wringing his little hands and screaming. As I had no experience, I imagined that if he did nap during the day, this might interfere with his sleeping so well during the night, and so was not trying to make him nap. If he fell asleep in the day, within ten minutes of putting him down he would be awake again. However, when woke up at half two in the morning a few nights ago, I suddenly found myself in the position of having to choose whether to get him out of his cot and soothe him back to sleep, something I haven't ever really had to do since he was a few weeks old, and that I knew could start habits I would have to continue, or whether to check all his 'vitals' and then put him back in his moses basket and soothe him but not rock him back to sleep. I chose the latter, and it took nearly an hour of blood curdling crying and going into him at regular intervals before he would settle, but the next day I put him down, wide awake, for naps in his moses basket, and now, just a few days later, he is settling himself from wide awake without a murmer not just at night, but in the day too. Today, I had to wake him at nearly 8am for his morning b/f and again from his post=lunch nap after two hours. I'm not saying that 'sleep training' at this age is right, or for everybody, I just wanted to let you know what my experiences have been. Sorry to have rambled, just chuffed to finally have a happy, settled ds. Hope it might help someone else who might be in similar position.
