So my LO is 15 weeks. She is staying at home with dad while I work full time. She is breastfed and bottle fed breastmilk while I'm gone. I've been working 5 weeks now. She started yesterday screaming and crying hard. He said she wakes up, takes bottle and bum change then started crying but eventually napped. He tried to rock her..play time, etc. No luck helping baby stop crying or shed stop briefly then start again. Shes done this all day until I got home and I soothed her with boobie. But what can he do to get her to stop? Right now he eventually gets to the point where he puts her alone in bed to cry it out because his mental health is suffering and she cries most of the day. Though even doing that doesnt help cause she still cries 40 plus mins.
