Nice wearable blanket, but made no difference in sleep

This is a nice wearable blanket, but it made absolutely no difference in the duration or quality of my daughter's sleep. I wasn't hoping for much so it wasn't a big let down, but this is kind of an expensive product as far as sleep sacks go. She is almost 7 months and wakes 4+ times a night. My touch alone has never soothed her (she only wants to nurse) so maybe that's the problem. The weighted portion is pretty lightweight; I was expecting something a little heavier, but maybe for a baby it's more noticeable. Overall, it seems like a nicely made product, but I'm not sure it does what the company claims.
