# Baby Road Trip Planner

> On a long drive with a baby, plan a break about every 2 hours by day (AAP says every 2 to 3 hours, and every 4 to 6 at night), and take your baby out of the car seat at each one. Enter your driving time to see where the breaks fall, which ones need a feed, and when you'll really arrive.

## How it works

The planner splits your driving time into equal stretches no longer than your limit, starting at 2 hours for a daytime drive and 4 hours overnight (the short end of AAP's 2 to 3 hours by day and 4 to 6 at night), and puts a break of your chosen length between them, 30 minutes to start. A break includes a feed whenever your baby would otherwise go past their usual feeding interval before the next chance to eat, assuming a feed just before you leave; the interval starts at a typical value for the baby's age and can be changed. Arrival time is the departure time plus the driving and the breaks.

## Key facts

- The AAP advises taking a break every 2 to 3 hours on a day trip with a baby and every 4 to 6 hours at night, to change diapers or clothes or to feed your baby. [1]
- The AAP says never to breastfeed in a moving car, and that car seats should not be considered a safe place for a baby to sleep outside the car. [1]
- The AAP's family travel tips advise stopping to give yourself and your child a break about every two hours on car trips. [2]
- The UK's Lullaby Trust advises avoiding long drives with premature and young babies, taking regular breaks, and stopping straight away if a baby slumps forward in the car seat. [3]
- The Lullaby Trust suggests using a mirror to keep an eye on a baby when you drive alone. [3]
- A 2017 University of Bristol pilot study of 40 newborns in car seats on a rig that mimicked a car at 30 mph found that their breathing and heart rates rose and their blood oxygen fell. [4]

## Reference data

### Daytime drives

With the planner's starting values for a daytime drive with a 1- to 3-month-old: stretches of at most 2 hours, 30-minute breaks, feeds every 3 hours, fed just before leaving.

| Driving time | Breaks | Longest stretch | Feeds on the way | Door to door |
| --- | --- | --- | --- | --- |
| 3 h | 1 | 1 h 30 min | 1 | 3 h 30 min |
| 5 h | 2 | 1 h 40 min | 2 | 6 h |
| 8 h | 3 | 2 h | 3 | 9 h 30 min |

### A 5-hour drive leaving at 9:00 AM

| Stop | Time | Note |
| --- | --- | --- |
| Leave | 9:00 AM | Feed and change first |
| Break 1 | 10:40 AM to 11:10 AM | Feed and change, after 1 h 40 min of driving |
| Break 2 | 12:50 PM to 1:20 PM | Feed and change, after 3 h 20 min of driving |
| Arrive | 3:00 PM | |

## Frequently asked questions

### What is the car seat 2-hour rule?

It's guidance, mostly from UK car seat makers and NHS trusts, that a baby shouldn't stay in a car seat for more than two hours at a time. It isn't a US law or an AAP rule, but the American Academy of Pediatrics gives similar advice: take a break every 2 to 3 hours on a day trip and every 4 to 6 hours at night, and take your baby out of the seat at each stop.

### Why shouldn't a baby stay in a car seat too long?

A young baby's head can slump forward in the semi-upright position, which can narrow the airway. A small 2017 study at the University of Bristol found that newborns sitting in car seats on a rig that mimicked driving breathed faster, had faster heart rates and had lower blood oxygen. Breaks, and stopping straight away if your baby slumps, keep the time short.

### Is it different for newborns and premature babies?

Yes: keep their stretches shorter. The UK's Lullaby Trust advises avoiding long drives with premature and young babies where you can. In the US, premature babies are usually checked in the hospital before going home to make sure they can sit safely in a car seat for the drive, and AAP advises keeping their time in the seat to what travel needs.

### Can my baby sleep in the car seat on the drive?

Yes, in a properly installed seat with the harness snug, while the car is moving. Car seats aren't a safe place for sleep outside the car, so when you arrive, move a sleeping baby to a crib, bassinet or play yard.

### Can I take my baby out to feed while we drive?

No. A baby should be buckled in whenever the car is moving. AAP says never to breastfeed in a moving car: pull over at a safe place, feed, then buckle your baby back in before you drive on.

### How do I keep an eye on a rear-facing baby when I'm driving alone?

Use a baby car mirror on the headrest in front of the car seat, as the Lullaby Trust suggests for solo drivers. A glance at your rearview mirror shows your baby's face, so you'll notice if their head slumps forward and you need to stop.
