When did you transition LO to the crib?

AB

How old was your LO when you start putting them in their crib for naps and bedtime? Did baby sleep better in the crib? How long did it take for baby to get used to the crib? My baby is 3 months old and today I just put her in her crib for her first nap and she has been moving nonstop 🤦🏻‍♀️
