Sleeping in the Crib/Routine

It's been a while since I made a post, so I thought I'd do one about our new routine. We have a basic routine! It's exciting! Well, most days anyway.
Rowan goes to bed usually around 8:30. Sometimes it takes a couple tries to get her to sleep, but she's usually out for the night by 9:30 or so. And she sleeps! All night! Her average get up time is about 7am, which I like, but some mornings (like today), she's up at 6:30. Must be taking after her Grandmas who are all early risers. 7:30 is better for me though. Then we get up, she nurses, then goes back to sleep for 1/2 hour to an hour, giving me time to make coffee, pump and check emails or make blog posts. The rest of the day is still a little all over the place as for nap and nursing times, but I can't believe how lucky we are that she sleeps through the night. And I do think it's luck of the draw. I had heard that sleeping babies existed, but I only knew one person who had one.
We did have about a week or so that she was waking up at 5am or so and I couldn't figure out why. She'd been sleeping all night for a few weeks by then, then I realized: (this is a bit of a complicated story!)
It starts out when I was about 5 months pregnant and Gramma Lynne took me shopping for a crib, mattress and what ever else caught our fancy. (We got the crib, mattress, sheets and the softest, warmest little blanket that Gramma picked out.) We saw these things called "Sleep Sacks". They're basically a sleeping bag with arms for baby. Not a bad idea considering how much babies kick off the blankets and can't pull them back up again, but the way they're marketed had us laughing through the store. They basically tell you that this is what you need your baby to sleep in so that they don't choke and/or suffocate and die in their blankets. Now I know these things weren't around when we were kids and we all made it out of the crib alive. Not that I don't think it could happen. The poor little things are so helpless that it's possible, we just thought it was really goofy and playing on parents fears when you have a new baby. I also knew that a friend was making Rowan a quilt that I would want to use and we actually ended up getting 3 quilts, 3 fuzzy blankets and an afghan for her, so she's got no lack for blankies.
Skip forward to the gift we received from James' office, which had some great clothes and also one of these sleep sacks. James and I giggled as I told him about Lynne and I making fun of the sleep sacks in Toys R Us. We continued to swaddle Rowan in her fuzzy blankets and she slept fine, no smothering, but she would kick the blanket off no matter how tight I swaddled her up. Plus she was getting a heat rash on the back of her neck, her back would be very sweaty in the morning, but her feet were still cold. So one night we decided to try the sleep sack. Her feet stayed warmer and she slept through the night more often. Our upstairs bedrooms are quite chilly, so cold feet are the norm in our house. So we thought this was good and kept putting her in it. This being a Saskatchewan winter, as the weather got colder, we would add a blanket on top and because the sleep sack is fuzzy, the extra blanket sort of sticks to it and she can't kick it off. She stays toasty warm.
So the week or so that she wasn't sleeping all night: We weren't using the sleep sack! I finally figured out that she was getting cold and that's why she'd wake up. As soon as we started using it again, she started sleeping later again. Silly Mom!
So I now endorse the sleep sack, at least in our chilly house, but for very different reasons than the marketing. Such a learning curve to these little creatures!
