Thick Sleepsack suggestions

Sarah

Hi! I’m looking to size up sleepsacks for my daughter but I’m having trouble finding one that’s thick enough. And at this point I’ve looked at hundreds and I might need some mama help to zero in on some options lol

I have tried the nested bean 1.0 tog and the fabric is so thin and my LO seems to sleep terribly in it. But sleeps better in her thicker ones when I trade them out.

I need a 6-15 month option. Any suggestions?!
