She's 19. Too young, if we are all completely honest.
Last year, she was pregnant with her own DD who died sadly due to a miscarriage at 20 weeks. The pregnancy wasn't planned, although that wasn't making it any easier obviously. I am/was of course devastated for her so I know she's had a hard time. But she needs to be realistic in her choices, as hard as that may be for now.
Her boyfriend is nice enough but I'm not entirely sure he's right for her, for a number of reasons.
Thing is, even if she did let herself down and her prospects down by moving out and finding somewhere to live, that would at least be something.
But she wants to continue living in her large bedroom, with her en-suite. The house is quite big so we have space but her entitlement is so off.
The reason I know she's TTC is because I found a receipt from Boots on the side next to some Vitamins and my prescription I asked her to pick up. On it said Folic Acid. I take a further look and I find it in the cupboard. Upon confronting DD, she says she's very sorry but they feel TTC is the only thing that's easing their pain.
I said fine, (I was quite angry), but move out first at least. She says she wants to stay here. I said she really can't, with a baby. When asked if she also expected her boyfriend to move in too, she said she didn't expect that? To make matters worse yet, H has spoken to her over dinner apparently?! And he says he supports her decision... when speaking to him in private, I said this is absolutely NOT on, she isn't even willing to move out. He says we've got space 
and the room. I say no. He's very calm about this whole thing. It's actually infuriating. I said well I bet she still expected to come on holiday with us if she has a baby. He says why not?!
Truth is that H doesn't want to downsize and I do. We currently live in a 5 bed house. It's too big for us all. We also have a DS who's 11.
What on earth would you do? H is not supporting me in encouraging DD to find a space of her own. That's before we get into the fact that two 19 year olds are trying for a baby.
She has no proper job, despite very good A Level results. She chose to go to work in some admin role for the NHS and works only 4 days a week 'because it suits her well'. Her boyfriend works in property of some sort in an advanced apprenticeship, think he did a few before that. A
I'm so upset for her. I can't believe she's doing this to herself and us
