I have some divorced friends with a child and who do exactly that!

The cost of daycare is the reason why my husband cant have the children here whilst working full time or at least close to full time. Swiss pay 100chf per child per day for daycare. In sweden you pay 100chf per child per month.

Kids who go to school don't cost 2.000,- a month on daycare

No. They dont both go to school yet.

Salaries here are much higher than in Sweden, and you will be contributing towards the child care.

....and how much tax you pay in Sweeden and how much in Switzerland ?

OP could always have a couple more kids, move to Hungary and never pay income tax ever again.

But all of that is irrelevant. I echo most other posters here and reiterate that unless there are very serious concerns about the father, there is almost zero chance of a mother taking her children out of Switzerland and away from their father to live with her, if the father doesn't agree. Sorry.

I last Christmas had this discussion on a Swedish dining table.

Sweden:

0% on income part from 0 - 2.036 Chf
32% on income part from 2.036 Chf to 50.735 Chf
52% on income part from 50.735 Chf to 73.166 Chf
57% on income part for all above 73.166 Chf

7% of income up to 45.523 is mandatory for pension funding, and this 7% is tax deductible.

But that is not all, effectively if you earn 6.000 Chf a month while living in Stockholm you will after municipality, burial, earned income, county and state taxes have a netto salary of a whopping 2.877 Chf due to a total taxation of 52% on such income

Switzerland we all know (Well, I may hope so since we live here..)

So what do you get for paying so much tax?

Depends on your income. It is a social welfare state meaning the less you have, the more you get. To me their system is all about redistribution of income. If you are at the bottom Sweden is a financially better place than Switzerland, if you are the average worker I would not want to trade Switzerland for Sweden.

It isn't all that clearcut as it's presented here. One question is, for instance, if the father would take the children in if the mother were to leave without the children. See for instance this article by the Beobachter on two federal court rulings under the currently applicable law:

Case one) Five years after the divorce the mother (has custody) wants to move to Spain with the 7yr old daughter, neither speaks Spanish or has ties to Spain (other than the new partner, I presume). Father and ex-hubby objects.

It was ruled that it was "clearly" in the child's best interest to stay in Switzerland. The facts that the relationship wasn't stable yet and that neither speaks Spanish nor had any ties there were the deciding factors.

Case two) Mother has custody of the children (ages 4 and 5) and wants to move back to Austria, they were living in the German speaking parts so language was not an aspect. The mother was main "Bezugsperson" (the most important person for the children) and the caretaker. The father objected. It was ruled that she can take the children with her, not least because the father doesn't want to take care of the children.

Cheap child care

As I understood it, one of the factors courts may take into account before permitting relocation is the geography and the transport connections. The more quickly and directly the child can reach the "other" parent, the more reasonable the court may find the idea.

Since the courts are about the best interests of the children, they look at factors such as:
If the children move away, will they be able to have both parents attend the school play and parents' evening? Will the child be able to make his/her own way to visit the parent he/she isn't living with, within an hour or a few hours?

The eldest one, as I understood, was born in Switzerland or was at least the reason you moved, together. He/she would be in kindergarten by now, I think
Is that right? And the younger one, (who was born here) will, depending on month of birth, start kindergarten in August this year or next. By which time the elder woukd be at school.

Some kindergartens' and schools' timetables are still annoyingly, dispruptively, all over the show irregular. That, of course, makes it harder for the stay-at-home parent to find a part-time job. But it does get better, in terms of more schools adopting block times, and much better once one has established networks of other parents to swap lunch duties. And great that their father could be at home for them on some days.

I appreciate that you come (as many of us do) from a different culture with a different perspective, but the above is the usual way it works in Switzerland.

Against that, if you wish to persuade any judge, you're going to have to demonstrate why ANYthing you could offer the children, in Sweden, could make up for their being deprived - by geography - from this kind of ordinary, everyday contact with their father.

Factors like being better able to afford to buy a house abroad are unlikely to tip the balance, since that is a bald fact for many foreigners.
