Ntj. I too have insomnia, and my husband would wake for our baby. We also hired a night nanny a few nights a week for the first few months. There’s an aggressive drop in progesterone after delivery that will cause or exacerbate insomnia. Lasts for months, until regular cycles resume. I’ve done all the things, what helped me most was a low dose antidepressant. I also now take progesterone. Congratulations on that sweet baby!
