so....what happens when a sleep regression is over?

i finally figured out that my 3 month old is going through a sleep regression. i didn’t realize because he’s been doing well at night, just during the day when he’s screaming from over tiredness, until last night.

it’s been getting progressively worse for almost 2 weeks now, we had 2 very bad days then yesterday he did actually pretty good, and that’s when he switched to waking up throughout the night. that’s what made me research and realize it’s a sleep regression.

so...it IS just a phase, right? will he go back to sleeping well at night again and not screaming from being tired? please tell me there’s a light at the end of this tunnel..

he’s always been such a good baby and it’s really killing me to hear him scream and cry from being tired, and i just feel like i’m missing something.

what happens when it “ends”? do things go back to normal? will he go back to sleeping 7 hours at night? thank you mommies for the help
