My son used a sleep sack for the first time yesterday/last night, and it got me wondering what you all dress your lo's in when they wear a sleep sack. I put my son in a long sleeve shirt and he seemed to handle that well. He is napping now and is wearing the sleep sack with a sleeveless onesie. He again seems to be doing well with that. I am using the Halo sleep sack for reference.

Curious to hear your responses. Thanks!
