What else can I take, other than Colace, to help with bowel movements and hemorrhoids, that is safe while breastfeeding?

Another option you can consider is taking a stool softener like Lax-A-Day or Restoralax, which are safe to use while breastfeeding. These products are usually well-tolerated and don't cause dependency or bloating. It's recommended to take it daily for best results. Simply mix the powder in a glass of water, as it is tasteless. The recommended dosage is 17g of powder mixed in a cup of water. You should see an improvement in a few days.
