Self soothing and sleep regression

My LO is 3 months old and she can self soothe herself to sleep. She doesn’t always do it, sometimes she’s fussy. But usually these days I feed her and burp her, sing to her a little then lay her down. Even if she’s wide awake when I put her down, she soothes herself to sleep within a few minutes.

I know I’m blessed but I’m dreading the possibility of the 4 month sleep regression.

However, I was reading that babies who know how to self soothe don’t go through the regression. Is this true??? *keeping my fingers crossed*
