Back in the trenches at five months

My baby is five months and 2 weeks and everything just seems so so hard again. I had this beautiful time from 3-4 months (there abouts) where my baby would sleep fairly well, was cooing and so smiley and was (comparatively to now) easy peasy. Around mid Jan the sleep regression hit - for us it can be frequent wakings but most often a split night (baby is awake for at least 2 hours at some point). I have always done nights entirely alone - my partner snores like a rhino and I can’t sleep without earplugs which I don’t want to do in case I miss something.

She’s also developed pretty bad eczema, she’s fussy a lot, she seems to want my undivided attention (before I could pee or unpack the dishwasher while she played with a toy for a bit), she will only contact nap or nap in the stroller, theres barely any self settling anymore. She’s also fussy, she’s crying more again (I think teething or her skin) and I just want her to feel better but I am also mourning the easy little bubba I had for a short while.

I don’t know what I’m looking for here but I’m just back to finding it so so hard again. Today I just cried all day.
