Sleep regression?

Courtney

My babe is almost 14 weeks and was sleeping through the night from 8:30-3 then 3:30-7 until a few nights ago with last night being the worst. He was up every hour or two fussing and literally was moving all night long! Is this the dreaded 4 month sleep regression I’ve been hearing about?! If so how long did it last for your babe?!
