Nothing about the first hundred days is what the antenatal class implied. The baby feeds more often than you expected, sleeps in shorter bursts than you were promised, and the questions you actually have at 4am are not in any book you bought.
This is the newborn chapter of our young parents guide to Singapore. It covers what is normal, what is not, and what has a deadline.
Week One: What Normal Looks Like
The first week has its own rules, and almost all of the panic in it is about weight and nappies.
| Day | Wet nappies | Dirty nappies | What else |
|---|---|---|---|
| Day 1 | 1 or more | Black, sticky meconium | Very sleepy is normal |
| Day 3 | 3 or more | Turning greenish | Milk usually comes in, jaundice often appears |
| Day 5 | 5 or more, heavy | Yellow, seedy | Weight loss bottoming out |
| Day 10 to 14 | 6 or more | Several a day | Back to birth weight |
Losing up to about 10 percent of birth weight in the first days is expected. Not being back to birth weight by two weeks is worth a call. Jaundice in the first week is common and usually mild, but jaundice on day one, or a baby who is deep yellow, floppy or feeding poorly, is a same-day medical problem.
Log feeds and output with the Feeding Log and the Diaper Change Counter. In the first weeks, the nappy count is the single most useful number you have.
Do the paperwork in the first month
Register the birth, then enrol in Baby Bonus and open the Child Development Account. CDA First Step is credited once the account is open, and co-matching only starts counting after your own deposits. Every week the account stays unopened is a week of matching you are not earning. The Baby Finance Guide lists the full sequence.
Feeding: Volumes, Cluster Feeds and When to Worry
Newborns feed eight to twelve times in twenty four hours. That is not a sign anything is wrong. Their stomachs are tiny and breast milk digests fast.
- Cluster feeding in the evening is normal. It peaks around two to three weeks and again around six weeks, which happens to be when most parents conclude their supply has failed. It usually has not.
- Formula volumes go by weight, not age. Roughly 150ml per kilogram per day for a full-term baby, split across feeds. The Formula Feeding Calculator does the split for you.
- Combination feeding is a valid choice. Many Singapore mothers move to it around the end of maternity leave, and it is not a failure.
- Breastfeeding costs you calories. Several hundred extra a day. The Breastfeeding Calorie Calculator gives your number, and eating too little is a common cause of supply dips.
- Get help early. Lactation consultants are far more useful in week one than in week six. KKH and NUH both run services, and many polyclinics can refer you.
Track sessions with the Breastfeeding Calculator, and see the Feeding hub for latch problems, pumping schedules and returning to work while still nursing.
Sleep: What Is Realistic in the First 12 Weeks
Newborns sleep fourteen to seventeen hours a day, in stretches of two to four hours, with no day and night rhythm at all for the first six weeks or so. The body clock starts forming around eight to twelve weeks. Before that, there is nothing to train.
Longest realistic sleep stretch by age
Typical ranges for healthy full-term babies. Plenty of normal babies sit outside these and still turn out fine.
Safe sleep in Singapore has one local wrinkle: heat. A room around 24 to 26 degrees, light cotton layers, and no loose blankets, bumpers or pillows in the cot. Baby on the back, every sleep, until they can roll both ways on their own.
Check the setup with the Sleep Safety and Environment Evaluator, log patterns with the Nap Tracker, and read the guide to baby sleep in Singapore heat before you buy a swaddle sack designed for a European winter.
Confinement, Help and the Fourth Trimester
Confinement is a real part of the Singapore experience, whether you follow it strictly or loosely. What matters is that you get rest and food you did not have to cook, not which tradition you follow.
| Option | Rough cost | Best for |
|---|---|---|
| Live-in confinement nanny | $3,000 to $5,000 for 28 days | First baby, no family nearby, night help needed |
| Catered confinement food | $1,500 to $2,800 for 28 days | Family helping, but nobody wants to cook |
| Part-time help plus family | Varies widely | Second baby, older child at home |
| Just the two of you | Free, but costly in sleep | Both parents on leave at the same time |
With four weeks of paternity leave and Shared Parental Leave on top, more Singapore couples can now overlap their leave for the hardest weeks. Check what you are entitled to with the Parental Leave Calculator before you spend on help you might not need, and price the whole first year with the Baby Expense Calculator.
The Warning Signs Worth Memorising
Most newborn worries are nothing. These are the ones that are not. Any of these means the same day, not the next appointment.
- Fever. A rectal temperature of 38 degrees or above in a baby under three months is an emergency, even if they look well.
- Breathing trouble. Grunting, flaring nostrils, ribs pulling in, or long pauses.
- Feeding refusal. Several feeds refused in a row, or a baby too sleepy to wake for feeds.
- Dry nappies. Far fewer wet nappies than usual, or a sunken soft spot.
- Colour changes. Blue lips or tongue, deep yellow skin, or an unusually pale and mottled baby.
- A cry you do not recognise. High pitched, weak, or inconsolable for hours.
Keep the Temperature Tracker handy for fever patterns, and read the Infant CPR and First Aid Guide once now, while nothing is happening. The newborn warning signs page has the full list.
The first hundred days end with a baby who smiles at you, sleeps in longer stretches, and has a rhythm you can plan around. Almost nothing that felt permanent in week two is still true by week twelve, which is worth remembering at 4am in week two.
