My Personal Perspective:
It has never happened to me, but 12 month's worth of daycare and medical expenses is a significant surprise. Whether you were aware of the medical or child care expenses or not, your responsibility for a portion of medical and childcare expenses for your child still remains a legitimate obligation and it will not disappear. Besides food, cloths, shelter, toys, and diapers, it is known that children need medical and childcare services.
With that said, I anticipate you will have to pay your portion of those medical and childcare expenses, but probably through a schedule of set payments in conjunction with 100% of current and future monthly medical and childcare expenses as they are incurred.
To prevent being surprised in the future, be as proactive as you can (i.e. visit medical and childcare provider, know your child's medical history, know your child's childcare provider), stay current with financial obligations, and set aside a set amount for unforeseen expenses. #Sacrifice and be the father you would want your child to know.
To prevent this from happening to "Soon To Be" fathers, once you become aware you may potentially become a father, immediately adjust your spending habits, life style, estimate the expenses associated with having a child (e.g.
child support, medical, and child care), and save like crazy. #Sacrifice and be the father you would want your child to know.
