2 year old started wanting a pacifier

Nadia • Miami ,FL

So my son has been really cranking lately , I assumed he was teething his second molars .

He is 22 months old and he randomly found a pacifier in the drawer and for the last few days he has only been sleeping with it .

I never really gave it to him as a baby aside from a few times and he didn't show too much interest in it but now he only sleeps with it .

Has anyone gone through this with a toddler picking it up so late ? Should I do something about it or expect it to just be a phase
