Anyways, I noticed some reviewers were concerned about them being sleeveless, but they're made that way on purpose so that your baby doesn't over heat. (If you check out any SIDS info, they'll tell you to make sure not to do that). And they do come in cotton as well, for warmer months, although, I didn't have a need to use them much in the summer. As for problems with a child using this when they're able to stand or move around, I too was concerned, but found that my son has no problem standing up in his crib and he can crawl around fine when wearing it. They are a bit pricey, but for the function it serves and the peace of mind I have with it, it's worth it. This is definitely one item I highly suggest for anyone with a child under 1 year.

PS- I couldn't find any sizes larger than medium at B-R-US, so I ordered my XL online thru sugarbearz.com. Hope this helps.

Baby Essential  Jan 01, 2005
By Jennifer Akiyama
I discovered the Halo sleep sacks with my first baby and it was a dream come true. My son is a very restless sleeper and would kick off all his blankets and then wake up because he was cold. The sleep sack has kept him warm and sleeping for much longer stretches.

I only wish I had discovered it sooner.

Also, for parents concerned with SIDS (who isn't?) it is a huge relief not to worry about your baby suffocating on this blanket.

I enthusiasitacally recommend this product and have bought them for many friends having babies.

Reduce SIDS and Soothes fussy babies - a bed-time "Volvo".  Jan 06, 2006
By Alpha "Jason's Mommy"
Babies/children are always curious and don't like sleeping much since it reduces their "nosy" and/or get-into-trouble time.

Our family love Sleepsacks and we consider them Volvos, because of their safety value::

(1) Reduces the possibility of SIDs - not necessary to have a quilt or blankets in the crib with your baby when he/she is in a sleepsack.

(2) Soothes fussy babies - my nephews and nieces were always ready for Mr. Sandman as soon as they are in their sleepsacks - probably because of the "cocoon"-like feeling (so similar to their time in their mommy's womb).

They can roll around (once they are older, of course) and still sleep through the night safely, so you can get some sleep too without worrying about potential dangers in the crib.

Get 3 (2 small and 1 either Medium or Large) and you should be good to go. The newborn size is better suited for preemies. The choice for Medium or Large is negotiable because babies grow at different rates.

A safe alternative to blankets  Aug 02, 2005
By Morgan's Mom
With SIDS to worry about, I really do sleep more soundly at night knowing that my baby is warm but not at risk of being smothered by a loose blanket. The bottom-to-top zipper really is convenient for diaper changes, and while the sleepsack did shrink somewhat in the wash, that really hasn't affected its fit on our baby. We went from a fleece sleepsack (infant size) to a cotton one (medium) when the weather started getting warm. Our baby is big (14 lbs and 25 inches at 12 weeks), so we got a medium (one size larger than recommended) hoping it would fit all summer. We shouldn't have worried. The sizes are very generous, but even a very big sleepsack works - there's enough room to grow into without being loose enough at the arm- or neckholes to cause tangling or a smothering hazard. It's perfect for summer nights that are just cool enough that we want to be sure that the baby's feet and legs stay covered, even if her nightgown rides up. Overall, I wouldn't trade the sleepsack for a regular blanket, and I highly recommend it to all parents of infants.
