Patient's question:
What is wrong with a baby who is over forty days old and doesn't like drinking formula or sleeping? The baby recently switched to a new formula and suddenly doesn't like drinking milk anymore. As soon as the nipple is put in their mouth, they keep spitting it out. They are not getting enough to eat and are unwilling to sleep. They cry very badly whenever they are fed. What could be the reason?Doctor's answer:
Based on your description of the symptoms, a baby around forty days old is quite sensitive to formula. If you switch to a different formula, they may not like it. Children develop a sense of dependency, and a sudden change in the taste of the formula might leave the child unadjusted, making them reluctant to drink it. It is recommended not to use a formula that the child particularly dislikes, or to wait for a while to see if their preference changes. Breastfeeding is the best option; only when the baby is well-fed can they sleep soundly.
