Sleeping habits/routines

Brittney • 👪 love my family!
To all the moms out here.  I need some advice. 
I would like to old your little one was before you started having them sleep in the crib. First time mom and My little one was in a bassinet for the first 3 months but since he is rolling and outgrowing his bassinet, it's time for something bigger.  How did you make that transition or did they sleep with you for awhile...? I would like any and all advice or tips that would help me please! I'm curious as to how you all did it.  I know it takes time but anything helps! 
Thanks in advanced!!
