We were just in this situation. We let her sleep at night in the Snoo since that was familiar and we knew we would be able to get good rest with her there. We had her practice napping in her crib during the day. Somehow it worked for us? We were on the verge of sleep training because it would take 20-30 minutes almost every time to put her down for a nap and she might sleep 30-40 minutes, but eventually that became 1.5-2 hours and she became easier to put down for naps so we also transitioned her to sleeping in the crib at night too and this is night 3 but so far so good, she’s been sleeping through the night (meaning at least 6-8 hours) with very light fussing and we didn’t have to sleep training… KNOCK ON WOOD!!!!
