We had huge sleep issues with
DD from about 6months to 10months.
To help at night, we moved bedtime forward to begin with from half 9 to half 8, then half 7 and now she's most often in bed at half 6. We then put in a proper bedtime routine - dinner at half 5, bath, cuddles, bit of a play in her room, then story, BF (or bottle when we swapped to that) then in cot, awake and pat till she went to sleep - this used to take an hour - now its's nowhere near as long. Once we did this, her wake-ups during the night also dropped - it went from 3-4 times per night, down to 1-2 and now at 13months, she is sleeping thru probably 3-4 nights a week ( i never thought that this would happen!) Mind you, she is an extremely active bub, and is already on one day sleep only.
However, day naps were much harder to get sorted - your
DS sounds like
DD in being a very alert bub. We tried a routine (shorter version of her night time, minus the bath) but no matter what I did, she would still be screamin in her cot and would not calm down. I ended up extremely stressed by this (not helped by some of the nurses on the parents hepline mind you) and went to get help. I got into a day service for help with settling and luckily, I had a young mw who talked absolute sense to me - basically, she told me it didn't matter if she still needed a feed to sleep during the day - as long as nights stayed consistent, daytimes I could whatever worked. In the end, I decided that long walks timed for sleep in the pram - when she was ready for a nap, I'd strap her in and she'd end up having great sleeps - well at least much better than previously (not the 2x2hr long naps that many of the mums in mum's group were having!)
Do whatever works and saves your sanity!
