Being a working parent is expensive.
Almost one-third of families spend at least 20% of their household income on child care, up from 18% in 2014, according to a survey of more than 1,100 parents by care service site Care.com. Weekly rates on average to take care of one infant are $565 for a nanny, $211 for a child care center, $200 for a family child care program, $367 for an au pair and $232 for an after-school babysitter, it found.
