I used the regular one and right now he's in the 50/50 with his left arm out ( he found his thumb). He never liked to sleep with his arms down and like to sucking is hand
We use one every night! LO hated regular swaddle because she likes her hands by her face. Highly recommend it... I also noticed that the size mostly affects the length so it's better to go up a size and she grew into it
Re: Love to dream swaddle
They run small so keep that in mind!
