Who breaks out of the miracle blanket? My LO! And I'm sure many others as well at around 4 months. I think it's really time to move him to a sleep sack this week. I'm afraid. Is he going to sleep through the night? That's my biggest fear. Is he going to scratch up his face? Another fear. I cut his nails weekly but it seems like it's not enough. I can't seem to remember when I moved my oldest but he never had a problem with sleep.

When did you move your LO to a sleep sack from a swaddle and did they have problems sleeping through the night? If so, how long did it take for them to get used to sleeping w/o a swaddle?
