If baby is rolling don’t put in merlin. You are suppose to transition out of merlin when they start rolling plus when you have to transition out of the merlin it’s like starting from scratch and so hard… again
I swear by dreamland sleep sack! You can try Facebook marketplace to get it cheaper second hand
@Emilie did your baby adjust easily to it? Mine hates when I put him in it an tries kicking his legs and gets frustrated and starts fussing and crying
The Merlin sleepsuit is super helpful for transitioning. Their arms are technically free but the padding keeps them pretty well contained. It saved us while we transitioned to a sleep sack.
