Breastfeeding My Two Year Old

My  kids have come down with a nasty cold recently. Both of them have never been so miserable before and when we went to the doctor, she said it is viral so no need for antibiotics. I am happy for that but it has been going on for about 3 weeks now so at times I wished there was a medicine that would help.
Being ill, my two year old doesn't have much of an appetite. He only had smoothies and breastmilk for a few days. It hasn't been very easy for me: Sleepless nights plus frequently breastfeeding made me very tired but at least it gives me peace of mind as I  know my boy  is still getting lots of nutrients by breastfeeding.
Do you know in the second year (12-23 months), 448 mL of breastmilk provides:
29% of energy requirements
43% of protein requirements
36% of calcium requirements
75% of vitamin A requirements
76% of folate requirements
94% of vitamin B12 requirements
60% of vitamin C requirements

Here is a lovely video I came across a few days ago.  The kids enjoy watching it as well.
