DS2 is 6 weeks old and has been a good sleeper up til now- spontaneous 2-2.5 hr nap at lunchtime, settling well in the eves and sleeping til 10pm, only waking up 3-5 times a night. Unfortunately this has all started to change - he's now waking up crying after 45mins/1hr of a daytime nap and needs either a boob or a pinky to suck on to get back to sleep. Similarly in the eve, he now needs to be fed to sleep and sometimes needs the pinky too. I read somewhere that 6-8 weeks is when babies start having defined sleep cycles where they rouse a little after 30-45mins and this is when sleep associations occur as we try to get them to go back to sleep. I had a terrible time with DS1 culminating in CC at 6 mths since I had PND and hadnt slept for more than 45min straight since the birth and I know this was because I set up bad sleep associations with him (in his case needing to be pushed around in a pram) I'm desperate to not make the same mistake again as I don't think I could do CC again. Does anyone have any tips on how to settle a baby without setting up bad habits/sleep associations? I'm loosely following baby whisperer and have a bath, massage, feed bedtime routine. Also DS2 hates being swaddled and patting him when he is lying down crying in th cot does absolutely nothing for him and seems to make him worse.
