The 4 month sleep regression was so bad with Charlie but then we sleep trained so it didn't last long. I breastfed Olive until she was 26 months so sleep was pretty easy up until that point!

With both kids it was just after after 2 when we transitioned them out of the crib. Pretty much for a year plus there were bedtime shenanigans and fighting bedtime with both kids.

What was the hardest stage sleep-wise for you?
