I've posted a few topics recently about being in the midst of the dreaded 4 month sleep regression. It's been about 3 weeks now. DD will sleep 2.5-3 hrs when first put to bed, then she's up about every 1.5-2hrs until around 3am. Then she'll either be up for a while (i.e. ~90 min) or she'll just fuss on the boob for a while, making it impossible for me to sleep. I've started bedsharing more and more because all she seems to want is boobs- if I lay with her, she'll at least let me rest (sort of).
We have to be out of the house for work (full time) most days by 6:30am so her 3-4am starts are really having an impact on my ability to function.
I've done a ton of research and it just seems like opinions are so polarized about whether to just let her do what she wants and continue bedsharing/all night nursing until she "grows out of it". In the meantime, I'm snapping at DH constantly since he's typically snoring away when all of this is going on. (In fairness to him, he always offers to stay up with her but since all she seems to want is my boobs, I tell him it's not worth it.)
What have you done that's helped you make it through this phase?
