The childcare issue is a big problem that doesn't have easy answers and is very similar to the elder care problem. At either end, there are people who need to be cared for and the carers have largely joined the workforce - meaning somebody must either leave the workforce, or they must import help (either via the live-in program) or otherwise. Those jobs don't pay a lot - but at the same time, there isn't a lot left over after paying for it either. Periods of caring also tend to be very transitory (ie. 6 years duration or less, mitigated by school entry or death). Further, there are gender and equity issues that make solving the problem something that requires thoughtful analysis of the policies put in place.
Maternity/Parental leave solves the problem for a large number of people for the first year of life, as does compassionate care leave somewhat. However, I'm not sure if "opting out of the workforce" is really what is desired or even what is optimal. For many, the ability to work part-time enables better care sharing than a complete opt-out, so perhaps the facilitation of job-shares might be more helpful. For others, perhaps encouraging further skill development during periods of caring might be a good strategy.
Ultimately - the burden needs be met - and the choices on how it is met may have significant impacts. Which is why a cohesive strategy that helps those facing these challenges is a good plank in an election platform for the island.
