I've heard many different view on this? Why did you decide to or not decide to? Is it better for cool weather babies or does it not matter? Ours will be an Oct/Nov baby. Personally, I'm claustrophobic, so I wouldn't like it, but to each his own...
March 2011: Off Nuva, cycle back to "normal" for me: No periods since 15 years old.
June 2011:Provera&50 mg Clomid; Progesterone:0.7

Met with RE:No Clomid response, begin injectables Sep
5 mg Letrozole and Ovidrel in the interim month. Cut out running (was a distance-runner), cycling, eliptical. Restricted to weight-training, walking, pilates. Brain MRI normal. Being physically over-stressed is the reason the body stopped producing prog.
Late Sep 2011: Menopur, Ovidrel,& IUI (10.10.11):BFN-Great injectable response: 2 mature, 6 near mature, many smaller; Problem: 9 cysts! Dr: IUI too uncontrolled for number of viable eggs & age. On to IVF! IVF ER 12.6: 37 mature eggs, 27 fertilized, froze all to avoid overstimulation; FET 1.22 (2 Grade 1)=BFN; FET 2.22 (3 Grade 2)=BFP!

Re: To swaddle or not to swaddle?
We swaddle for sure at night!! I have started swaddling once a day for nap time to get a better nap. When he's not swaddled, he only sleeps for 45-1.5 hours.
When he's not swaddled, he flails his arms and wakes himself up.
We swaddle DS at night and did for naps as well for the first month. He sleeps much better swaddled. Now, if I lay him down unswaddled for a nap, he usually startles and wakes up within about 20 minutes whereas at night he'll sleep at least 4 hours and sometimes closer to 6. We'll continue to swaddle until 4-5 months.
As far as weather, he was born in February, so obviously it was colder then - we dressed him in a sleeper and then swaddled. Now, as it's warming up quite a bit, I'll dress him in a onesie and then swaddle him so that he doesn't get too warm.
We definitely swaddle and have from day one. We use a blanket during the day and at night a halo swaddle sack(i am too worried about blankets coming undone when I am sleeping). When she falls asleep during the day without swaddling, she will not sleep long as she startles awake easily, arms flailing and whatnot.
If she is in the carseat (in the car or a snap n go) she can sleep a long time there too, probably because it is so snug fitting. Also when I am wearing her in the ergo she sleeps well, which is again similar to swaddling.
oh and while you wouldn't like it, that doesn't matter - babies spent 9 months in the womb being all snug and not having much room to move, especially towards the end. When they come out, the world can be an overwhelming place, and swaddling can help re-create that womb experience and make them feel comforted.

You may be claustrophobic, but your baby definitely is not. He/she is currently in a very small space that will get tighter as baby gets bigger! We didn't swaddle at first because I didn't think he needed it, but he wasn't sleeping for very long stretches at night (typically only two hours at a time.) The first time we swaddled, he slept for four hours. Babies are used to their limbs being confined, and having their arms and legs free can actually be distressing for them when they're trying to sleep, because their arms flail if they get startled or move.
We have several SwaddleMes, and I felt really bad the first few times I put them on DS, because they kind of look like straitjackets for babies. However, DS would typically calm down as soon as he was swaddled, so it clearly wasn't bothering him. In fact, a few days ago, he was super fussy during the day, and I couldn't get him to calm down. Finally I swaddled him, and the second I velcroed it, he gave me a huge smile and stopped fussing. The tightness makes them feel secure like they're in the womb again.
The directions on the SwaddleMes say to dress them in light clothes under the swaddle and have the room at a temperature comfortable for a lightly dressed adult. We kind of adjust what he wears under the swaddle to what the temperature is like. On cold nights, we put him in flannel/fleece pajamas under the swaddle. On warm nights, we just put him in a onesie.
Swaddle, no question for us. He's a restless maniac without it. He'll literally sleep only 30 minute stretches max unswaddled. Swaddled he will nap for hours and sleep very long stretches at night. I cannot imagine how insane with sleep deprivation I would be without it!
I'm in MI, so it's chilly here at night. We usually swaddle him with a long sleeve onesie & socks.
We do not swaddle. She would toss and turn trying to get her arms free. She sleeps better without it.
