Can my 5 mo old baby eat food and drink water? Sometimes I'm worried about her feeding, she is on formula 4/5 oz every 3 hours

Sounds normal. Studies show that breast milk or formula alone supplies balanced nutrition for the first year +. Most early solid feeding pressure comes from the days babies were fed home made blends of boiled cow milk/karo & vitamins.At the time early supplements made sense, now they are overdone.Starting should focus on training baby to sit up & eat in preparation for his/her position at the table.
