Downs syndrome can be incredibly debilitating, or can be the total opposite, many downs children dont live very long (though some go on to live to 40 or beyond, though it is rare past that)
I think you need to think about a couple of things here
1. can YOU handle being the mama of a baby who may need you to bathe, feed and care for it much as you would a young child for all of its life (maybe 30 years)
2. How much do you think this will affect your other child? Can you cope with that?
3. If your husband is being unsupportive, then its probably best to think about how you will deal with both children, one of which may need heart surgery and other support well into its adult life, without him
I am sorry to be blunt here, but its important to be sure, i realise you say that you would find it hard to live with, but your existing child and any future children would have to live with it too x
there is a chance that you may get a child with downs who is in the able range, then this stuff wouldnt matter so much and having spent time with downs children and adults, i would say they enrich life so so much, they look at the world as innocent little beings and it is really beautiful
but a heavily downs child... can be awfully difficult and they can suffer from extreme heart defect and unfortuntly many dont last long x
bless you, what an awful decision to have to make, but i would not write off any possibility, termination is a horrid thing to have to consider but actually, if you have a heavily downs child who will suffer through life... well it is worth considering x
ask for some support and help making your decision, there will be trained councillors who can help you with this
so sorry xxx
