When I was separated from my newborn at the hospital during the first days of his life, I had to develop patience, trust, understanding, compassion, and express the colostrum so I could feed him those precious drops that come from the breast before the milk comes in.
In those moments of anxiety, when I spent minutes expressing to get one single drop, I practiced the following breath, which is actually in itself a very powerful meditation:
Inhale through the nose constantly during 20 seconds, hold the breath in comfortably for 20 seconds, and exhale through the nose slowly during 20 seconds. Do it as long as needed, for best results practice at least for 11 minutes. If to start with it feels too much, you can start with 10 seconds inhaling, 10 seconds holding and 10 seconds exhaling, and increase slowly until you breathe the 20 seconds on each part. This meditation was given by Yogi Bhajan and is called the one-minute breath. It builds up one’s patience, increases the lung capacity, clears the mind, connects to your heart centre and grounds you in your body. It can be practiced my anyone anywhere.

The second meditation I have been practicing is a meditation on the heart, given to me by Shiv Charan Singh to keep up through the sleepless nights and challenges of the 40 days after birth. It is a meditation which like the first one can be practiced while breastfeeding, and your baby, through your milk and your energetic connection, will also benefit greatly from it’s effects.
Inhaling through the nose in four equal and smooth parts, thinking each time sat, sat, sat, sat; and exhaling also through the nose thinking naam in one long and smooth stroke. While exhaling, you visualise yourself descending from your head to your heart, into your cup of prayer. This meditation builds up one’s capacity to trust the infinite, rely on the universal truth (sat) which lies inside of you in your heart, and also helps you build your intuition to listen to and trust your child. It’s a great practice to remain still and steady through all the challenges of life, and in the 40 days after birth it helps enormously with the patience of keeping up with your child and the unconditional love beyond all hard times (like the wakings during the night every hour and the crying spells, colic and nursing strikes).
