daughter wants to terminate at 16 weeks

Sounds like Hyperemisis Gravida and you and your daughter completely have my sympathy. My daughter went through this, spent most of her first 5 months in and out of hospital being rehydrated. I hope your DD's GP has referred her to hospital, they see HG a lot these days. There are websites and blogs for HG sufferers which may help her. I wish I could offer more for you but as you say it is her choice and I totally understand if she can not see the pregnancy through.

Poor girl, I understand how she feels - I had the most dreadful hyperemesis in both pregnancies. Many women, including the Duchess of Cambridge, are hospitalised with this condition.

Can she be persuaded to call her GP and ask for an urgent referral to see if the sickness can be dealt with?

How sad

It’s so sad, but I think that you have to separate your home situation from your DDs.

Sadly you can’t influence your daughter, I understand where you are coming from, but it has to be her decision, you can’t persuade her to keep going with the pregnancy because a GC would fill the gap in Your life.

I really think that you have to sort your home life out first, get yourself on an even keel with your husband, Stay together or part, maybe that will help you to come to terms with your DDs decision.

I am sorry though, I was sick and ill for 9 months with both of mine and it was really awful, it must be difficult for her to think straight if she is away from her OH, is there any chance that he could get home and be with her before she goes ahead with the termination?
But I also think that to keep a secret between you is a bad idea.

That is all so sad, sending kindest thoughts to you and your daughter

What a sad situation.

Your poor daughter.

I don’t know what to say how very sad

oh this is so so hard, just do not know what to say- apart that I feel for you, and for her too. You will probably be 'blamed' and the baddie whatever you do. I am so sorry.

I don't know what to say but didn't want to ignore your heart breaking post. All I can think of to say is please don't feel ashamed.

This is your D's decision. Does her H know of her decision or will she be telling him that she miss carried. I ask because if she is not going to be honest with her H, this may be too big a secret for either of you to keep.
