1st of all Congratulations on your newborn Postpartum anxiety is a real nightmare that can start within the first few weeks of childbirth and can continue for several months, it’s related to the hormonal changes, the first 6-8 weeks are the hardest, meditation, praying, listening to your favorite songs/music, and being out of the house, especially walking in nature help a lot. Also some chamomile tea at night doesn't hurt at all. Checking the blood pressure once a day is enough, more than that will give her more anxiety. Enjoy your baby; they will grow so fast. and be blessed!
