11 month baby do not take any solid food

my 11 month baby do not take any solid food and he looks very weak now. please advice on how to feed solid food to baby and which food we should start first. thanks.

Start with vegetable puree with little salt and turmeric (carrot, tomato, potato) in the afternoon. Give meshed banana,sugar, milk combination pureed in the mornng for breakfast. Give gathia flakes in the mouth and allow baby to chew. At nite give khichdi or wheat flour raab (diluted sheera), that wil make it full for the kid and will sleep well at nite.
