Milk contains fat, which is not conducive to the recovery of baby's diarrhea. It is best to give your baby a little salty rice soup or sugar salt water, which can prevent dehydration. Pay attention to supplement high-quality protein, such as skim milk, egg custard, tofu, lean meat, etc. Other supplementary foods include rice soup, rice flour, millet pumpkin porridge, yam porridge, rotten noodles, etc., which are apple-like, so you can boil apple water for your baby to drink. Avoid foods with high fiber content, such as vegetable puree and fruit puree.
