Woolino 4 Season Ultimate Baby Sleeping Bag - Merino Wool and Organic Cotton Universal Size Adjustable Sleep Sack for Baby - Two-Way Zipper Sleeping Bag (2-24 Months) - Navy Blue

I put off buying this thing for 6 months, due to price, and now I wish I hadn't waited.Apparently, in order to keep babies from going up in flames, infant sleepers have to be either fleece (which stops being fluffy after only 3 washes), treated with fire resistant chemicals (um, no), or snug fitting (itchy!). Well, I was cheating by buying super big sleepers for my son, and just letting him sleep with floppy footies. Unfortunately, now that he is 9 months, the "snug fitting" sleepers are ridiculously tight, and he was waking up with freezing feet every night, even the fleece sleepers-- which are 20 bucks a pop where I live, and have to be replaced every month, because they pile up. Plus, he started crying whenever I zipped them up, because who on EARTH wants to sleep in a compression sack-- I certainly wouldn't. I itch when my tank tops are too tight!So I finally pressed the button and got this little gem. I've used wool baby products before, so I would encourage anyone to "lanolinize" this every few months, which helps the wool resist moisture/pee, softens it, and allows you to wash it less, and makes it hang dry quicker. However, this is as soft as Egyptian cotton and the company says it's washable, so you don't really need to. (I always handwash with a little Dr. Bronners and lanolin, though, personally).This bag has sturdy snaps (no scratchy velcro), which allow it to be comfy but form fitting on the upper body. Double snaps on the side comform to a smaller or bigger baby. Even though my son has TONS of room in the foot area to grow into, I have zero concerns that he will get twisted up in it... and he's a hard-core squirmer. Even with his constant caterpillar scooting and rolling, he's never complained or been uncomfortable in this, and when he does wake up at night, his feet are WARM, because he's basically sleeping in a giant mitten. It has a zip at the bottom for nighttime changes or, possibly, if you're kiddos feet are getting hot. There's an open/close spot at the crotch area for safety belts to go through. Plus, this saves money, because (underneath) the baby is sleeping in the same one-sies or shirts he/she would be using during the day, so you don't have to keep getting longer foot-ie pyja, or replacing the scratchy fleece ones.Don't hesitate to buy this wonderful product. It's cozy, quality construction, and economical, in the long run.Update: still going strong at 2 years, with occasional washing, but no special treatment whatsoever. It's even been thrown in the regular, high heat dryer several times, although I wouldn't recommend doing so regularly. My son sees the sack and knows it's time to "snuggle up" for bedtime. Love it!

Love this sleep sack!If you're anything like me - first time mom over here - I was obsessed with whether baby was too hot or too cold from day one. Overheating or being too cold can be uncomfortable for baby and prevent them from sleeping, and severe overheating has been linked to SIDs. Thus, keeping baby at the perfect temperature - especially as a newborn when they're bodies are still not able to regulate - has been a constant concern of mine that required much thought and effort and trial and error with what temperature to set the thermostat in our house, how many layers to dress in, etc.For my now 7.5 month old, we've been through a number of swaddles and sleep sacks. We live in Los Angeles, so pretty mild weather but still gets chilly in the winter, enough to warrant turning on the heat and obviously, very warm in the summer. We keep the baby's room between 68-72 degrees, which is the recommended range (an indoor thermostat is a must for baby's room! We have this one and we're happy with it: ThermoPro TP55 Digital Hygrometer Indoor Thermometer Humidity Gauge with Jumbo Touchscreen and Backlight Temperature Humidity) In the warmer months we've been dressing baby in a lightweight 100% cotton footLESS pajama or long-sleeve onesie with pants no undershirt, no socks and in the cooler months, footed 100% cotton pajamas, sometimes the slightly thicker organic ones, and no undershirt (please, don't dress baby in polyester, especially not at night, it does not breathe and can cause overheating). The sleep sack comes with a guide as to how to dress for what weather. We basically just followed itThis is a very high quality sleep sack, from the zippers to the snaps, to the soft material and design, the weight is really nice, not too heavy but heavy enough to feel cozy. On a typical spring to summer evening, the temperature in the nursery can range from 72 to 68 or sometimes even 67 degrees farehnheith. The sleep sack keeps baby cool and dry, and warm and cozy. Just perfect. I'm not attributing the fact that baby sleeps really well ENTIRELY to the sleep sack but I do think it has helped. And also has alleviated my concerns and give me peace of mind. Priceless.

I was a bit hesitant to spend so much money on a sleep sack. I mean, really! But then I did some calculations and realized that having to buy two other sacks for every stage of my baby's growth for the next two years was going to cost just as much if not more than just buying two of these.When they arrived I was a little concerned that they would be itchy, even though they felt really soft, but it turns out my baby loves them. It's really true what they say about Merino wool - it's very fine and doesn't trigger reactions like other kinds of wool, and although it's lightweight it can be used in a variety of temperatures. We get wild fluctuations of temperature here, and the very best part of this is the little card that comes with the sleep sack. It has a simple thermometer on it, as well as a guide to how to dress your baby under the sleep sack to correspond with different temperatures, so your baby doesn't get too warm or too cold. It's seriously great! I have used that guide multiple times a day, and it gives some peace of mind, considering that dressing your baby over-warm increases the risk of SIDS.I also love that it is really adjustable. The buttons under the arm holes are great at keeping it in place and making it fit just right. And we haven't found the extra fabric at the bottom to be a problem at all.For us this was the perfect sleep sack to transition to after we finished swaddling, at about 3.5/4 months. Our baby has been totally happy and comfy, and getting him into his sleep sack is an important part of his nap/bedtime routine, that has really helped him develop good sleep habits and associations. Highly recommended!
