If you follow a vegan diet or one that does not include any forms of animal protein, you or your baby might not get enough vitamin B12 in your bodies.
In a baby, B12 deficiency can cause symptoms such as:
• Loss of appetite
• Slow motor development
• Being very tired
• Weak muscles
• Blood problems
You can protect your and your baby's health by taking vitamin B12 supplements while breastfeeding. Talk to your doctor about your vitamin B12 needs.
