He finds out the baby growth rticle which says:
As a 1- to 3-month-old, your baby will likely continue to grow at a similar rate, while also gaining 1 to 1.5 inches (2.54 to 3.81 centimeters) in length per month. These are just averages. Your baby may grow somewhat faster or slower, and is likely to experience growth spurts along with other times of slower growth.
How many feedings a day your baby gets. A breastfed baby may feed 8 to 12 times in a 24-hour period; bottle-fed babies usually eat less frequently, perhaps every 3 to 4 hours.
How much your baby eats at each feeding. A baby generally nurses for at least 10 minutes, should be heard to swallow, and should seem satisfied when done. Bottle-fed babies eat about 3 to 4 ounces (88.72 to 118.29 milliliters) a feeding during the first month, with an extra ounce (29.57 milliliters) per feeding for each additional month.
How often your baby urinates. Babies should have at least 4 to 6 wet diapers a day.
How many bowel movements your baby has each day, and their volume and consistency. Breastfed babies' stools should be soft and slightly runny. The stools of formula-fed babies tend to be a little firmer, but should not be hard or formed. Frequency of bowel movements depends on age and type of feeding.
