Size up! Well, I started with a bigger size, but we we are 5 months and still loving it. DD wants to roll but doesn't want to sleep on her belly and I don't anticipate that changing soon. I wish I could remember when DS started sleeping fine despite rolling.

We transitioned DD to just sleeping in a sleeper (was being Velcro swaddled) at a little before 4 months. It was seamless. I'd go ahead and transition instead of buying something new.

That's about when we tansitioned out of the Merlin as well. He was outgrowing and it just seemed to make more sense to bite the bullet.
It took a few days for him to get over the excitement of being able to move. Haha. But it overall was quick and painless and he was sleeping just as well if not better a few days after stopping it.
Oh and I started with just naps, no suit. Then when he seemed comfortable with that I stopped at night. So night time sleep wasn't very impacted.

If LO has always been a good sleeper, I would transition out of it. We did Swaddke Me and then used nothing from about 3.5 months onward. She started belly sleeping around 5 months and I was ok with it at that point (we still put her on her back first of course).

Ok.... those of you who transferred from a swaddle (we use velcro Swaddle Me) to nothing in the crib... please tell me the wisdom of your ways!! We're going through kind of a sleep regression now (I just posted a thread), but once we get through THAT, I know I have to start thinking about the swaddle situation. DS is 12 wks and cannot sleep without the swaddle AND still sleeps in the RnP!

@Jennibenni: a sleep sack isn't anything like a Merlin. The Merlin really restricts their movement but a sleep sack is just a blanket. It's very roomy.
We went from the Merlin to a sleep sack and never adjusted the room temp.
We use the Babydee Sleep Nest sleep sack, it's also thick like the Merlin but breathable so they don't overheat. It's like a sleep sack duvet or comforter He sleeps so well in it, but still able to move freely and he even walks around his crib in it.
Also, I find that the sleep sack really helps with setting the nap/bedtime routine. He knows what it is and that it signifies nap time/bedtime. A sleep sack will continue that "ritual" from the Merlin.
