Baby merlin magic sleep suit, yay or nay?

Melissa

Trying to find the best solution for transitioning my almost 4mo lo out of the halo swaddle sleep sack. He's struggles and is restless trying to get his hands free, which he eventually does. I tried the love to dream sack (kind of snug on his neck) and tried the sleep sack with arms completely out but he is still startling himself. Trying to decide between the magic suit or a zipadee-zip.
