Sort of, but not really. Obviously it's possible for the man to be the care giver, but there is a significant unavoidable amount of time required by the mother through pregnancy and recovery that makes it more logical for men to be primarily in the non-caregiver role, but sure it does violate some people's narrative even it's been the majority case since the inception of humanity.
