Just wanted to share my issues and what has been working for me with myLO...
I have been working really hard on independent sleeping - putting him down drowsy but awake. It has been making such a difference in his sleeping. My DS sleeps for naps and nights swaddled - haven't had much luck weaning it, but we have been letting him have one hand free in a Love sack, which keeps his arm up by his head. It has worked so well the last 2 weeks. He's suddenly able to settle himself back to sleep most times, unless he wakes up hungry.
I also tried to move my DS bedtime so many times! I eventually got it to 6:30 but he would wake every hour until about 10:30. I decided to give that up, and now I just base it on what time he wakes in the morning. If he wakes up at 7:00am, I aim for a 7pm or 730pm bedtime.
As for napping, stretching my DS's A time, and giving him lots of physical activity has seemed to help me. It's funny because if I am off even 5 minutes, I get a 45 minute nap. If I'm bang on with his A time, I get 1hr45min or 2hrs. The quality of A time seems important when developmental stuff is happening, as they want lots of practice on talking, crawling, rolling over, etc.
These little ones are a puzzle!
So my advice is to work really hard on teaching self settling and independent sleep. Also, I just relaxed about what time bedtime was, and just tried to make sure the day wasn't too long. sometimes the day is 12hrs, sometimes a little less.
Fingers crossed for you.
