Sure it goes to everyone, but I think that's okay. Some parents would still choose to both work, and use their monthly check to pay for daycare. I think the important thing is freedom to choose.
I do think we need to encourage raising children specifically, but if UBI is assigned regardless of age, then that effectively works out to the same thing - parents will just use those checks for childcare costs, and having more children would translate to more checks.
