You are trying to work out whether your childminder’s group size is normal, or whether it is actually over some legal limit nobody told you about. How many children can a childminder have before something changes, and is your childminder within that number? It is a fair thing to wonder, especially with a mixed-age group where the headcount is not always obvious at a glance.
The good news is that how many children a childminder can have is one of the more precisely defined rules in Irish childcare, once you know the actual number.
Key Takeaways
– A childminder can mind up to 3 preschool children and 6 children in total before Tusla registration is required.
– The childminder’s own children under 15 count toward that total.
– Going over either threshold means registration is no longer optional.
– The rule exists to keep groups small enough for real one-to-one attention.
How many children can a childminder have: the limit
How many children can a childminder have and still be exempt from Tusla registration? Up to 3 preschool-age children, and no more than 6 children in total, counting the childminder’s own. Go over either number, and registration becomes compulsory regardless of the current transition period. That is also why do childminders have to be registered is really a group-size question as much as a legal one.
This is the exact rule set out in Tusla’s childminding guidance, and it is worth knowing precisely rather than roughly, because the difference between exempt and required to register comes down to a single child.

What counts as preschool age
Preschool generally means children not yet enrolled in primary school, so typically up to around age five, though the exact cut-off follows the child’s actual school starting age rather than a fixed birthday.
Mixed-age groups and why the count still applies
A childminder minding one baby, one toddler and one school-age child after 3pm is still counting three children toward the total, and the baby and toddler both count toward the preschool limit. If the childminder has two children of their own at home during the day, those two are added to the total as well, which can quietly push a small-looking group over six. Citizens Information’s overview of childcare regulation covers how this sits alongside the wider regulatory framework.
What happens above the limit: registration and ratios
Once a childminder minds more than 3 preschool children, or more than 6 children in total, Tusla registration is no longer voluntary. This is true even during the current transition period, which only applies to childminders operating within the exemption thresholds. Wondering whether childminders have to be registered more generally, beyond just group size, is worth reading if you are still working out the bigger picture.
How many children can a childminder have: quick scenarios
| Group | Registration required? |
|---|---|
| 3 preschoolers, no own children | No, exempt |
| 2 preschoolers + 1 school-age + 1 own child (4 total) | No, exempt |
| 4 preschoolers | Yes |
| 3 preschoolers + 2 own children + 2 school-age (7 total) | Yes |
Seeing it laid out this way makes the trap clearer: it is easy to stay under the preschool limit while quietly going over the total-of-six limit once older children and the childminder’s own family are counted.
Why the numbers matter for quality of care
The ratio is not arbitrary paperwork. Smaller groups mean more actual attention per child, faster response to a child who needs something, and a calmer overall day. When you are assessing a childminder, ask directly how many children they mind and what ages, not just whether they are registered. Our guide to childminders in Dublin covers the wider set of questions worth asking alongside this one.
Once you know what a reasonable group size looks like, you can find a Garda-vetted childminder on TrustedCarers.ie and ask every candidate the same direct question about their numbers.
Frequently asked questions
Q: Do the childminder’s own children count toward the limit?
A: Yes. A childminder’s own children under 15 count toward both the total-of-6 limit and, if preschool-age, the limit of 3 preschoolers.
Q: How many babies can a childminder mind at once?
A: Babies count as preschool children, so up to 3 babies or preschoolers, within the overall 6-child total, before registration is required.
Q: What is the ratio for a registered childminder?
A: Once a childminder registers, they can mind larger numbers under Tusla’s registered childminder ratios, which extend beyond the 3-and-6 exemption limits that apply to unregistered childminders.
Q: Can a childminder mind 4 preschoolers without registering?
A: No. Four or more preschool children means Tusla registration is required, regardless of the total headcount or the current transition period.
