Anyone try the Merlin sleep suit?

My daughter is usually up once between 1 and 3 to eat then up again around 4 or 5 but not because she's hungry, we think she gets cold after kicking out of her swaddle, if she lays in bed with my husband who throws a ton of heat she'll go back to sleep and we have to wake her at 6 when it's time to start the day. Just looking for something she can't get out of that will keep her warm enough.
