I have heard of mothers taking supplement for vitamin B to help boost their energy. However, I do not know of anyone who has tried that. You can also try some of these suggestions in this article (http://www.webmd.com/parenting/family-health-12/energy-tips-moms) which includes drinking more water, taking a bath or shower, take a break for yourself, exercise, eat a healthy breakfast, keeping blood sugar steady, changing your clothes, sleep, spending quality time with your child. Personally, I think getting as much rest as possible is important. Get help from your loved ones so that you can have some sleep. Take care!
I was an caffeine addict before my birth. So i still maintain my one cup of coffee a day. Secondly, i also take in a bottle of chicken essence a day. It gives me additional energy to sustain.
I heard that, eating fish(non-veg) will increase breastmilk for mum. It's totally depends upon food, what type of food are you having.
