Great guys, thanks! I really think it works great and she loves the way it feels. And helps us avoid pacifier, which I'd really prefer not to use. She is not swaddled so she can and does find her hands too. And yes, we ony use it for naptimes and bedtime (even naps in stroller).
Is it confusing to her though that it's a burp cloth - so therefore involved in eating too? Should I use different material burp cloths for eating and only these for sleeping? The ones she likes to sleep with are the Durdee cloths (can be diapers, bur cloths, etc).
Thanks for alleviating my worries.
