With the comment of maternity leave is: It is not a vacation! Just the opposite
It could be the hardest time of a woman's life! Recovering from birth, lack of sleep, taking care of a newborn plus other kids and rest of responsibilities, etc.
Then I refer you to "We have to assume that the expectant parents considered all angles of how they were going to cope with a 2nd child. If they didn't; that was irresponsible and is down to them to resolve by paying for child care."
This may possibly come as a shock to you but this isn't the first generation to ever have more than one child to care for! For many of our generation we didn't have the support of parents stepping in to help. Nor did we have husbands or partners who were entitled to paid paternity leave; we were lucky if they got a few days with us. The lack of sleep, taking care of a newborn plus other kids and rest of responsibilities, etc is nothing new; it's no more difficult now than it ever was! We just had to get on with it and be grateful if a grandparent could pop in from time to time. Deciding to expand your family is big decision and the responsibility for their ongoing care is your responsibility alone. If you can't cope; don't have more children. You have no entitlement to your parents taking over routine child care on a regular basis. Any assistance you do get is a bonus to be grateful for.
When a political leader lies on their CV - can you trust them?
