I expected some backlash but I can take it as well.
My son does all the cooking as I have severe arthritis in knees and limited mobility. He also does a lot of the running around things without claiming carers allowance. Fortunately my daughter is not violent, BUT some can be and it is awful.
It is the MIL I feel sorry for. Fortunately my daughter has a care package (2 1/2 hours a day) with a regular team of carers and we have plans in hand for when I pass away. DD needs 24 hours a day care and I step up to do all the personal care. It is the MIL who needs the sympathy.
My son is not married but neither does he hate women. Two of his previous girlfriends have gone on to do nurse training - one with the mentally handicapped - and are still in touch with us. I know where he is coming from. Your SIL has a family who do help (even if she has to claim the benefits as your MIL loses any Carers Allowance after reaching retirement age - as I have).
What upset him was the fact that I have NO family help - they all disappeared when DD was diagnosed, but my late mother had all the other grandchildren to stay overnight and provided the usual grandmother duties but cut mine off. I am not bitter as it is just a fact of life, and we have met some brilliant people some of which are still a part of my 'family' and we have watched their children grow up and cannot wait to join us for Christmas.
It is said that it takes a village to raise a child. It takes an extra special village to raise a disabled child. DD is my child, her brother's sister, but she is happy even though she cannot understand the pressures she puts on us. It is bloody hard work, and relentless, with no breaks or time off, even when I am ill or when her father died from cancer.
Your children will learn that not all children are born normal and some of those who are not need a lot of extra care. Just think. A disabled child can happen to any one of you - even a grandchild - and I hope with all my heart that we have a compassionate enough society to accept this and help without blaming others for what they do or not do. The people who come into my home are brilliant and we have a laugh (and cry a few tears occasionally) and help each other out. I admire them all and have brought much joy and forever will do. One day you might need a 'family of carers' and I hope they will be as brilliant as mine.
My rant over. Please feel free to comment
