Most children can take more responsibility for themselves as they age. Some disabled children cannot. Some children will always require less sleep, wake frequently and not be safe on their own or require medical support during the evening essentially in this sense these parents have the baby sleep years forever or until they stop caring for their child.
At some stage most children are expected to support themselves financially. Those with complex needs can't, they'll never work. Their benefits mainly go to the LA (unless they get chc funding which is being refused more and more) so parents are still expected to feed and clothe them.
These children cannot be left alone, they cannot get to school or home by themselves, can't do basic self care for themselves. So parents have to do it fir them until they stop caring for them. Imagine changing nappies for an adult with pubic hair and hormone impacts. We're not talking about babies we're talking about fully grown adults who can be strong and bigger than their parents.
Many parent carers have to take reduced hours at work or give up work all together. Think about the imoact on pensions, mortgages, savings etc it becomes nearly impossible for most.
I think many of these posters can't imagine what some of us have to deal with, with years of sleep deprivation.
I think the country/ gov have a choice on how we spend money and while i do think there are massive cuts and changes that can be made to dla/ pip/ childrens services/ adult services i don't think cuts to those who need the most support and are most vulnerable is the place to start.
