I've been in this situation. The opening time is not too long, and there is no problem during the warranty period. Later, I tied it tightly with a clean bag and put it on the fresh-keeping layer of the refrigerator, and it wouldn't either. I only gave the baby Heinz rice noodles for two months. Later, he asked people to go to the countryside to dry grind six kilograms of rice noodles, mainly rice, with glutinous rice, coix seed, Gordon Euryale seed, lotus seeds, yam, etc., and grind them into rice noodles. Every time a few spoonfuls of rice soup are mixed and stewed in a pot. The nutrition is very good, and the baby will not get angry after eating it.
