Transfer to crib?

So my LO is almost 4 months. We are both sleeping great right now...except she is still right next to me in her rock n play. She will sleep 9pm-7am with waking to nurse once and then goes right back to sleep.

We had a reallly rough first 2 months with colic and hardly sleeping at all.

So I’m wondering if I should just keep soaking up the good sleep while it lasts or if I should attempt to transfer her now in attempt to potentially make it an easier switch?

I’ve been putting her in her crib for a lot of her naps already.. but she’s becoming more and more reliant on her pacifier though. I often have to put it back in her mouth if she stirs a little.

Just wondering other mamas thoughts or experiences..
