The newborn's first week: a calm parent's guide

The first week at home with a newborn is equal parts wonder and worry. You will be tired. Your baby will eat and sleep on a clock nobody else can read. And at some point, probably around 3 a.m., you will find yourself wondering, “Is this normal?”

Here is the reassuring truth: almost always, it is. Second- and third-time parents ask the very same question. Below is what to expect in these first seven days, what is worth watching, and the handful of signs that mean it is time to pick up the phone.

Feeding

Newborn feeding looks chaotic from the inside and is usually going better than it feels.

Breastfed babies typically nurse 8–12 times in 24 hours. Look for at least 15–20 minutes of active sucking per session and 5–6 wet diapers a day by day five.

Formula-fed babies usually take 1.5–3 oz every 2–4 hours in the first week. Try not to force a schedule. Feed when your baby cues, with rooting, hand to mouth, or fussing.

A few signs that things are on track:

• Baby wakes on their own to feed
• You can hear or see swallowing
• Baby seems settled after a feed, rather than still rooting frantically
• Steady weight gain after day 4–5. Babies are typically back to birth weight by 2 weeks

Sleep

Newborns sleep 14–17 hours a day, in stretches of 2–4 hours. They do not yet know night from day. That is a skill that develops over weeks, not something you can teach in the first one, so try to rest when you can rather than waiting for a rhythm to arrive.

Safe sleep, every single time:

• On the back, on a firm flat surface: crib, bassinet, or pack ‘n play
• Nothing else in the sleep space. No blankets, pillows, bumpers, or stuffed animals
• Room sharing, meaning the same room but a separate surface, is recommended for the first 6 months

Diapers

Diaper counting is unglamorous, and it is the single easiest way to check at home that feeding is going well.

• Wet: 1 on day 1, rising to about 6+ by day 5 onward
• Stool: Black tarry meconium for 1–2 days, then transitioning to mustard-yellow and seedy by day 4–5 in breastfed babies

The cord, the circumcision, and all that peeling skin

Newborn skin and healing can look alarming and is usually completely ordinary.

• Umbilical cord: Keep it dry and open to the air. It usually falls off in 1–3 weeks, and a few drops of blood when it does is normal.
• Circumcision: Petroleum jelly on the gauze with each diaper change for the first 5–7 days.
• Peeling skin and tiny white bumps (milia): Both are normal and resolve on their own.

When to call, and when to call 911

Most of the first week needs patience rather than a phone call. These signs are the exceptions, and they deserve same-day attention. Call your pediatrician for:

• A rectal temperature of 100.4°F (38°C) or higher in a baby under 8 weeks. This one is always urgent, at any hour
• Difficulty breathing, grunting, or a bluish color around the lips
• Fewer than 4 wet diapers in 24 hours by day 5
• Refusing to feed for more than a few hours
• Yellow color spreading down the chest, belly, or legs (jaundice)
• A floppy or unusually sleepy baby who is hard to wake for feeds

Call 911 for trouble breathing, persistent blue color, seizure-like movements, or unresponsiveness.

The most important thing

Trust your gut. You know your baby better than anyone else does, even at one week old. If something feels off, say so out loud to someone who can help. In the first week, there is no such thing as a question that is too small.

Newborns are usually seen within the first 48–72 hours after hospital discharge, and again at 1–2 weeks. Your child’s current pediatrician or the hospital’s newborn follow-up clinic can arrange those visits.

Luma Pediatrics is opening in late 2026 in McKinney. If you are expecting, or your baby has just arrived, we would love to welcome you when we open. Until then, we hope this guide makes a long week feel a little shorter.
