U1 to U9: The Checkup Schedule Nobody Fully Explains Up Front
Germany's U-Untersuchungen are a structured series of free pediatric checkups, U1 through U9, and each one has a specific window it needs to happen in rather than a loose timeframe. U1 happens immediately after birth, U2 falls between the 3rd and 10th day of life, U3 between the 4th and 5th week, U4 in the 3rd to 4th month, U5 in the 6th to 7th month, and U6 around the 10th to 12th month, roughly the child's first birthday, six checkups packed into the first year alone. After that, the pace slows to roughly once a year: U7 around 21 to 24 months, U7a around 34 to 36 months, U8 around 46 to 48 months, and U9 around 60 to 64 months, age 5. The early exams, U1 through U3, focus mainly on catching illness or physical malformations early, while from U4 onward the emphasis shifts toward identifying developmental delays, physical, cognitive, and social, at each age-appropriate stage. Participation is voluntary and the exams are free, but there's a real catch: showing up outside the designated window for a given checkup can mean your Krankenkasse won't cover the cost, so the specific timing genuinely matters, not just eventually getting each one done.
The Official Rule
Germany’s U-Untersuchungen, a structured sequence of nine pediatric checkups labeled U1 through U9, aren’t a loose “get your kid checked periodically” recommendation, each one has a specific, defined window it’s meant to happen in, and that timing is worth taking seriously rather than treating as flexible.
The first year alone accounts for six of the nine checkups, a genuinely front-loaded schedule. U1 happens immediately after birth. U2 falls between the 3rd and 10th day of life. U3 comes at the 4th to 5th week. U4 at the 3rd to 4th month. U5 at the 6th to 7th month. U6 arrives around the 10th to 12th month, roughly your child’s first birthday. That’s six distinct checkups before your child turns one.
| Checkup | Timing window |
|---|---|
| U1 | Immediately after birth |
| U2 | 3rd-10th day of life |
| U3 | 4th-5th week |
| U4 | 3rd-4th month |
| U5 | 6th-7th month |
| U6 | 10th-12th month (~1 year) |
| U7 | 21st-24th month (~2 years) |
| U7a | 34th-36th month (~3 years) |
| U8 | 46th-48th month (~4 years) |
| U9 | 60th-64th month (5 years) |
After the first year, the pace deliberately slows to roughly one checkup annually. U7 lands around 21 to 24 months, U7a around 34 to 36 months, U8 around 46 to 48 months, and U9 around 60 to 64 months, age 5. This isn’t a reduction in importance, it reflects that the most rapid period of physical and developmental change is behind your child by that point, with annual monitoring considered sufficient going forward.
What’s actually being checked shifts meaningfully as the sequence progresses. U1 through U3, the earliest exams, focus mainly on catching illness or physical malformations early, this is the window where a genuine medical issue is most likely to first become visible. From U4 onward, the emphasis shifts toward developmental delays specifically, evaluating whether a child’s physical, cognitive, and social development is tracking appropriately for their age, rather than primarily screening for acute medical concerns.
Participation is voluntary and every checkup is free, but there’s a real, practical catch worth knowing upfront. Showing up notably outside a given checkup’s designated window can mean your statutory health insurance (Krankenkasse) won’t cover the cost of that specific exam. The timing isn’t just a suggestion for organizational tidiness, it has a real financial consequence attached if you drift too far outside it.
What Real People Say
Parents managing the first-year schedule specifically describe underestimating how frequent the U1 through U6 checkups actually are until they’re in the middle of it, six appointments within twelve months is a genuinely demanding cadence for a family also adjusting to a newborn, and the practical advice that comes up repeatedly is setting calendar reminders well ahead of each window rather than trying to track it from memory.
The coverage risk tied to missing a window is less widely understood upfront, and it comes up in practical discussion as the detail worth confirming directly with your Krankenkasse if you’re ever unsure whether you’re cutting it close on timing.
Step by Step
- Mark all nine checkup windows on your calendar as early as possible, ideally right after birth, given how front-loaded the first year is.
- Book your Kinderarzt appointments with enough lead time, especially for the closely spaced early checkups, U1 through U6, rather than waiting until you’re already inside the window.
- Bring the Gelbes Heft (U-Heft) to every single appointment, this is where results get recorded and where you can check the specific age-appropriate content for each upcoming U.
- If you’re approaching or past a window, contact your Kinderarzt and Krankenkasse promptly rather than waiting for the next scheduled checkup.
- Expect the pace to slow after U6, roughly annual checkups from U7 through U9, and adjust your planning rhythm accordingly.
Compliance Note
This page explains the general German U-Untersuchungen schedule and its typical focus areas, but this is not medical advice, and your child’s specific care should be guided by your Kinderarzt. For your child’s exact schedule and any timing concerns, consult your pediatrician and Krankenkasse directly.
FAQ & Common Pitfalls
We missed the exact window for one of the early checkups by a couple of weeks. Have we lost coverage for it?
It's worth checking with your Krankenkasse directly rather than assuming either way, but the real risk is genuine: showing up notably outside a checkup's designated window can mean the statutory health insurance doesn't cover the cost of that specific exam. If you realize you're close to or past a window, contacting your Kinderarzt and Krankenkasse promptly is worth doing rather than waiting until the next scheduled checkup and hoping it isn't an issue.
Why are there six checkups packed into the first year alone, and then it slows down so much?
The first year is when the most rapid physical and developmental change happens, and it's also the period where catching a genuine illness, malformation, or early developmental concern makes the most difference for early intervention. Once a child is past that first year and following an established developmental trajectory, annual checkups are considered sufficient to track ongoing development without needing the same intensity of monitoring.
What's the actual difference in focus between the early U-exams and the later ones?
U1 through U3 are weighted toward catching illness or physical malformations early, this is the period right after birth where a real medical issue is most likely to first become visible. From U4 onward, the emphasis shifts toward developmental delays specifically, checking whether a child's physical, cognitive, and social development is on track for their age, rather than primarily screening for acute medical issues.
