that's how it works in Czechia, except you can stay at home 3-4 years (!), so once one child is old enough to be accepted in kindergarten (age 3), you are usually having the other one, so essentially mothers usually stay at home 5-6 years with two kids

mind the parental leave welfare (literal translation Maternal vacation / materska dovolena) ain't that amazing, although it's also not that low - first 27 weeks it's paid by your employer (if you had one prior giving a birth), that one is pretty high based on your salary (I think only mother can take it, not sure) and then you are eligible to receive parental allowance (rodicovsky prispevek) - 300K CZK (12K EUR) which can be used as fast/slow as you want up to 4yo kid AFAIR, so it will essentially cover 2 years of decent income or 3 years lower welfare

since my wife wasn't employed in EU prior giving birth, we were not eligible for Maternal vacation welfare, only for parental allowance, which we applied since birth for both kids and I was actually the applicant since they don't distinguish between gender of recipients of alowance

after these years then if you don't have high enough income you are also eligible for child allowance (pridavek na dite), but that one is not worth mentioning, it makes like 20-40EUR per kid per month, so makes really difference only for poorest families, since you have to go to bureau 4 times a year to prove your low income to get this joke

edit: updated terminology to better distinguish between welfare kinds
