How do I start transiting my baby out of being swaddling? I ordered him a zipadee zip sleep suit and he hates it. The second his arms go up he wakes up right away. I tried to do the one arm out of the swaddle and he did the same thing. He would scream until I put him back in the swaddle. He’s beginning to learn how to roll over and he’s almost five months old so I really want to start getting him used to sleeping without it. He refuses to sleep without it and I don’t know what to do😩
