I'm trying to figure out how to time LO2's sleep transitions (basically from Rock n Play to crib, and also from swaddle to...something, maybe zipadee zip). He's 11 weeks now and sleeps fully swaddled in the RnP for nights and most naps (although recently I've been working on getting him to nap in the crib a bit). He starts full-time daycare in 2 weeks and I'll be back at work the week after.

I'm trying to avoid the horrible experience we had with LO1, where we transitioned her right around the same time we started daycare/work. That led to about a month of horrible sleep which got even worse after the 4 month sleep regression hit. At the height of it, she was waking literally every sleep cycle (8-10x per night). DH and I were destroyed and we finally had to sleep train at 5.5 months.

LO2 sleeps somewhat better than LO1 did at this age, so I can't shake the temptation to get him in his crib now before the 4 month regression hits him (if it does) but that would basically be the same timing as with LO1 and I wonder if it's too many changes at once.

I have no idea when he'll outgrow the RnP but he's fine for now and shows no signs of being able to roll over so the other part of me is tempted to just keep the status quo until after he's been at daycare awhile and possibly to ride out the 4 month regression. But I keep hearing that it's easier to transition them earlier than later so I keep going back and forth in it.

Just wondering what has worked for others.
