Expert Reviews

What reviewers liked

We’ve been using these since baby was 3 months old (he’s 11 months now). They are easy, safe and keep him warm. What more could you want?
We like the fact that they’ve been worn and tested with care, and the security that comes with buying from a unique, established brand like Burt’s.
This wearable blanket is super durable; thanks to the combed and ring-spun. Its zipper opens from the bottom, so you can have an easy time changing diapers.

This sleep sack is longer than others, allowing for lots of extra legroom and making it a good choice for longer babies or for those who want to get the most use out of their baby clothes.
I also love that it is wide enough for her to move and wiggle around (she never really enjoyed being confined) and the best part… it zippers from the top down.

What reviewers didn't like

I thought this would be a good transition from a swaddle, plus we tend to keep our heat pretty low (65ish) and I was worried he was too cold. It's a lovely pattern and material but we found that fleece pj's worked better for keeping him warm.
Some moms felt the sizing was too large.
A little large, especially for newborns
- Ah Joo
Although there are many things to like about this sleep sack, many users note that the fabric is much thinner than anticipated, and doesn't provide adequate warmth in colder homes or climates.
