Is there a hormone shift around 4 months post partum or something? I am struggling with ups and Downs, But wouldn’t really classify it as anxiety or depression. It’s hard to explain, but I go from feeling frustrated and overwhelmed about my sleep deprivation and just everything going on (baby + working full time) to very optimistic and happy and not worried about it at all. I just feel a little up and down and not sure if it’s the hormones or just the lack of sleep. For context, my LO doesn’t sleep more than 30 min at a time unless held. But when held, then I don’t sleep.
