Question..

full price theyre about $80 but theyre sized 0-6 months 6-18 months, so considering how long u use them for its well worth it.
baby bunting just had them on special for $62!!

LJ, I've seen them for sale in the Quokka.

If you go to best & less you can pick up similar things for about $20. They are like dressing gowns that zip up & closed at the bottom. I used them alot. They aren't as thick as grow bags, but they do have sleeves in them as well.
DS hates having blankets on too. When he's asleep I'll put them on, but they usually don't stay on for long. Drives me nuts when he mostly sleeps between us!
Just make sure he's dressed warm enough & don't worry too much about the sheets I guess
