Our lives are so busy these days, but I would encourage you to take the time to really develop a bond with your baby. It will be invaluable after birth. The best postures for a very short prenatal practice are cat/cow pose – to warm up and stretch your spine and sun salutations – modified for pregnancy and including downward dog (which can be practiced up to 35 weeks and balances the hormonal system). Sun salutations work with every muscle in the body. Be sure to always practice a relaxation – Savasana – after the poses. That is essential. In fact, if you only have time to do one thing, practice Savasana. You will feel so much better for it.
