We are in a predicament. Childcare costs are out of control and we literally lose an entire wage on childcare and more . I am the higher earner and we can survive off my wages and at least DD aged 18months isn't passed from pillar to post and can have some stability . My husband thinks being a SAHD is the best option. But then do I have to pay for his son? If CMS do the calculation on my wages we'd be hand to mouth. Husband seems to think that's not the case .... but is it ?
