If you are new parents, you may find that caring for a little baby is a daunting task. Constant worries about whether your child is growing in a healthy manner may give you sleepless nights. In a one month baby, development is a gradual process and happens each day. Knowing what to expect at specific time periods can put your mind at ease.


Growth of the Baby

Your baby will be born with excess body fluid and will lose this in the month following their birth, leading to a 10 percent decrease in your one-month-old baby’s weight. So, if there is some weight loss in your baby during the first few days, there is no reason for you to be alarmed. Their weight should increase within the next two weeks and after that, they will begin putting on weight more rapidly. They may gain anywhere between 14 to 28 grams per day during their first month.
If your baby is not gaining enough weight reach out to a healthcare professional to check for any underlying causes.


Baby Development

You can track your baby’s development by the week for a better understanding of how he is growing. Your doctor will measure your baby’s weight, height, and head circumference to determine his growth progress. You can also keep an eye out for other developments including vision, hearing, communication, and language abilities.
