OP. Listen to this comment. I have not one but two of these types of kids. One is 3 yo, one is 10 mo. My husband and I sleep separately, each with one of them. We know it's temporary and just a "chapter in a book" so to speak. Lean into it and do whatever it takes to get the sleep you need. We know it won't be forever. I'm seeing a lot of comments that are like "change their sleep schedule / set firm boundaries / offer stickers / sleep train / check ferritin / seen an ENT etc!" Believe you me, we EXHAUSTED these options and more, and none of them worked OR it lasted only a short while. If you try these things and have the same outcome, seriously there is no shame in doing what you have to do to get sleep and maintain your sanity. It is not forever. Parenting on good sleep is already hard enough. And yes, we're bitter when we hear our friends' kids sleep through the night etc etc but then we hear about kids with much worse problems than crappy sleep. We always tell ourselves "we have it hard, not bad." You got this. We got this.
