We've been in the process of slowly accustoming N to sleep unswaddled. He's been sleeping with one arm out of his wrap, but wakes up constantly if we take it completely away. Today I stumbled upon these really fabulous sleep sack's down at a local shop. They're so soft and cozy for this colder weather, unzip like a sleeping bag along the sides and snap at the shoulders, and are pretty thick and weighted. The one I picked up is this puppy, and it'll supposedly fit him until 24 months! N's slept like a champ for his naps today and is doing great so far tonight! Fingers crossed.
