When did your LO start sleeping with a blanket or a quilt (like the kinds that come in the baby bedding sets). I let K nap with an A&A blanket, but not at night. She sleeps with a sleep sack. My friend has never used a sleep sack or swaddle. Just used real blankets (not even the lightweight muslin kinds). Another friend's toddler refuses to sleep with any blanket, so they have to turn up the heat in the winter.

Just wondering about the blanket transition as LOs get older...
