Anemia in 15 month baby. Is found?

Hi doctors. I have recently done CBC on 3rd may of my baby . His HB is 8 Wbc 15900 Platelets 5.08 lacs RBC 4.18 million MCV 62.2 MCH 19.1 RDW 16.5 from above information which type of anemia is found ? His weight is not gaining from past 3 months (9.5-10kg range around) current  weight is 10 kg. Not any test done before CBC. Baby was born cs about 20 days before due date. All things were OK till before 15 days. ( as usual he got fever cold cough in every 2 month ) Before 15 days he vomit first ever thrice a day for two days and loose motions. And eat nothing these two days except breastfeed and little water. Since then he became lazy and due to medication he sleeps most of time a day. He hardly passes 2-3 urine a day. But spends 1-2 hours in walking rumoring here and there. But in last 15 days he is pushed 2 months back. Now he walks and falls often. My doc only saw CBC and gave medicine. So seeking advice What should other test should I do
