Is it normal for a 7 week old baby spit up just clear liquid?

Yes, it is relatively normal for a 7-week-old baby to spit up clear liquid, which is often just breast milk or formula mixed with stomach acid. This can happen due to the baby's immature digestive system or overfeeding. However, if the spitting up is excessive, accompanied by distress, or if there are other concerning symptoms, it's best to consult a pediatrician. Always monitor for signs of dehydration or other health issues.
