DD is 3 1/2 months old - she used to sleep every night in a swaddler. But now she is getting too big/strong for it and is busting out of it. So, I tried a sleep sack last night and it was a disaster! She went from waking up twice a night to waking up 7-8 times a night! My husband thinks we should just give it a few nights, but I think we should try a larger swaddle blanket. But, he thinks she will just bust out of that as well.

When did you stop swaddling? Did you find getting a bigger swaddle blanket was effective after 3-4 months?
