Procreator's remorse
The sense of regret after having children. It may stem from fear of making the wrong choice, guilt over extravagance, or a suspicion of having been overly influenced by friends, parents, or a partner.
Jim was on the fence about having children and once he did he was struck with a bad case of procreator's remorse.
