You can start foods at 6months old n above . Now she’s 10months old, yes go ahead. I started trying soft porridge at 8months old , try and error with all kinds of purée foods / porridge etc. If she’s a good eater , U also can cook soft rice Or congee instead then can give rice with soups when she’s able to chew properly:) then give snacks in between. When she’s 1 yo n above, you can give full cream milk too
Teething stages normally at 6m to 3 yo. So depends on each child at early or later . Some even has tooth at 4-5months.
