Thank you for choosing DoctorSpring.
Being a Vegetarian who is not consuming Dairy products puts you and your baby in a higher risk side for nutritional deficiency of Vitamins. You will need to take supplement. TThe Recommended Intakes (RI) for nutrients have a wide safety margin built in.
I will break it down for you here :
1.Energy — The energy cost of exclusive breastfeeding from birth through six months postpartum is 500 kcal/day. You can easily make it up by eating calorie rich food items like potatoes, sweet potatoes etc.
2.Protein — The additional protein requirement for the first six months of lactation is 25 g per day. Since you are not taking milk YOU WILL need make up for this by consuming protein rich food items such as Pulses.
3.Fat-soluble vitamins - Vitamin A does not need supplementation usually. But in certain population it is considered essential.
Vitamin D - make you and your baby get some sun exposure. You are taking 100mg Calcium + 220 IU Vitamin D which is anyway inadequate. You will need to take at least 500mg Calcium.
4.Vitamin B12: you are already getting sufficient B12 in your supplement. (around 10mcg will do) In addition you can have fortified soya and fortified cereals which are rich in B12.
5. Other Water soluble Vitamine - B1 , Folate. You will need to supplement these as per the recommended daily allowance recommendations.
6.Zinc: You do not require to take additional supplements. You can consume plant sources like beans, nuts, whole grains, fortified cereals. Availability of zinc from plant foods is lower than from animal foods, but plant foods are still a good source and is sufficient for you.
My recommendations would be :
1) Continue Prenate Mini - It will take care of Vitamin B6, B12, Folic Acid, Vitamin C, Biotin, Iron, Iodine, Vitamin D.
2) Take additional Calcium of 500mg per day (It is for you, not your baby)
3) Take care of Protein, Energy needs.
4) If you baby is Sun exposed (indirect exposure would do) Vitamin D supplementation is not needed. However do talk to your Paediatrician about VItamin A and D supplement for your baby. In certain population groups it is done. Since your Doctor will be the best person to decide on this based on local recommendations. Personally I would actually recommend one or two doses of Vitamin A supplementation.
5 ) Re Evaluate whether you really need to avoid milk altogether (This is important)
6) Fortified breakfast cereals, Soya milk , other nutrient rich food items to be included into your diet.
Hope this helps
